Best Man Will Miss Best Friend's Wedding Because His Girlfriend Threatens to Break Up If He Leaves Her Alone with Their Hypothetical Dog
A drama-free wedding was one couple's objective when they planned an intimate, out-of-town ceremony with just the maid of honor and the best man. However, this proved to be too lofty a goal because the best man's girlfriend caused drama anyway.
OP and her fiancé chose to have their wedding in a small city in Italy. The location was specifically chosen to avoid the drama their families would have brought if the wedding were held where they lived.
OP and her fiancé informed their wedding party that they could invite their partners to the wedding. The couple would shoulder the cost of the trip and accommodations for their guests.
Mike, her fiancé's childhood best friend and best man, invited his girlfriend, Courtney, to accompany him. The problem was that they expected to have a dog at the time of OP's wedding.
Mike asked if it was possible to book a dog-friendly hotel. OP and her fiancé apologized to Mike for not considering the dog and booked the pet-friendly hotel as requested.
Mike and Courtney's next concern was the dog's ability to withstand the four-hour drive to the city. OP and her fiancé asked if the couple had family or friends who could dog-sit for them.
Courtney dismissed the suggestion. Mike replied that Courtney would no longer attend the wedding to care for the dog.
The next day, Mike withdrew from the wedding entirely. He stated that Courtney did not want to be alone with the dog for an entire weekend, but she also didn't want to miss the wedding.
Courtney messaged OP and suggested that they reschedule their wedding or hold it in their hometown.

OP's fiancé asked Mike to reconsider his decision. Mike confided in him that Courtney threatened to leave him if he didn't stay with her and the dog that weekend.

The Role of Attachment in Relationships
Dr. Julia Roberts, a psychologist from the University of Chicago, discusses how attachment styles can profoundly affect romantic relationships. Individuals with anxious attachment may exhibit controlling behaviors, often stemming from a fear of abandonment.
This situation illustrates how one partner's need for security can lead to controlling behaviors that threaten the stability of the relationship.
OP's typically stoic fiancé was hurt by his best friend's decision and expressed his feelings to him.

Courtney messaged OP the following day as if nothing had happened. OP felt that she and Courtney were good enough friends for her to be honest about her disappointment.

Insights from Dr. Helen Fisher, a biological anthropologist, suggest that "attachment styles are deeply rooted in our early experiences and significantly shape how we respond to relationship threats." Understanding these attachment styles can be crucial in addressing maladaptive behaviors stemming from insecurity. Furthermore, Dr. Alexandra Solomon, a relationship therapist, emphasizes that "recognizing one's attachment style can lead to healthier relational dynamics and improved communication." Such perspectives can greatly inform therapeutic approaches aimed at fostering more secure and fulfilling relationships.
OP thought Courtney would apologize for all the issues she caused, but instead, she insulted OP. She called OP a bridezilla and stated that she wouldn't accept any apologies from her.

The dog is hypothetical and irrelevant. Courtney is merely using the dog as a tool to test Mike's loyalty to her.

Fostering Healthy Boundaries
Establishing healthy boundaries in relationships is crucial for maintaining individual autonomy. Couples can benefit from discussing their needs and expectations openly, creating a space where both partners feel secure in expressing their views.
Psychological research emphasizes that clear boundaries not only enhance mutual respect but also promote emotional safety within the relationship.
They are undermining OP's goal of having a stress-free wedding. The ceremony is months away, but Courtney's unreasonable demands are off-putting.

The absolute audacity of Courtney to demand that OP reschedule and relocate her wedding is astonishing. This woman has no shame.

Additionally, couples can engage in joint activities that reinforce their bond and mutual support. Participating in shared hobbies or experiences can create a sense of unity and help mitigate feelings of insecurity.
According to studies, couples who participate in shared activities report higher relationship satisfaction and greater emotional intimacy.
Mike needs to find his spine before Courtney permanently replaces it with jelly.

A Courtney-free wedding and birthday would be the best thing for OP right now.

Disinviting Mike entirely was the right decision. Courtney would have found a way to sabotage their wedding plans at the last minute, which would defeat the entire purpose of OP's intimate wedding.
OP's fiancé also needs to accept that he might not get his best friend back because Courtney's claws are dug too deep. He and OP can now look forward to their wedding since all this drama is behind them.
This woman truly expected OP to apologize to her after everything she had done. Perhaps Courtney's self-awareness is also on the way, just like the dog.

OP's update: Mike's mom was furious that he was missing his best friend's wedding. Courtney tried to save face and claimed she would have allowed Mike to attend the wedding solo if not for OP's rude message. Mike yelled at Courtney when she lied, causing her to cry, which made Mike feel guilty.

OP's fiancé told Mike he had already replaced him as his best man with one of their close friends, who happily accepted.

Courtney apologized to Mike for overreacting after his family reacted negatively to her actions. OP's fiancé told Mike it was too late, as he didn't plan to make any more changes to their wedding plans. Mike would miss the wedding, and OP's fiancé hoped it would show him how Courtney's influence on him could affect his future.
