Ending Friendship with Best Friends Ex After Secretly Dating: AITA?

A 27-year-old woman refused to play nice after her best friend’s ex started acting way too comfortable around her. Sarah and OP have been inseparable since college, the kind of friendship where you know each other’s secrets before you even realize you’re telling them.

Then Matt, Sarah’s long-term boyfriend, breaks up with Sarah. And suddenly, he’s “confiding” in OP, lingering a little too long, and sliding into flirt territory like he owns the place. When he finally admits he wants to date OP, she shuts it down fast, cuts off Matt completely, and tries to protect the friendship she values more than anything.

The problem is, Sarah found out, and now the question is whether OP saved the friendship or nuked it.

Original Post

I (27F) have been best friends with my friend Sarah (26F) since college. We've always been close and shared everything with each other.

Recently, Sarah broke up with her long-term boyfriend, Matt (28M). They had been together for years, and the breakup was tough on both of them.

After the breakup, I noticed that Matt started to act differently around me. He seemed more interested in spending time together and confiding in me.

I found it odd but didn't think much of it at first. However, over time, his behavior became flirtatious and inappropriate.

One day, Matt confessed that he had developed feelings for me and wanted to pursue a romantic relationship. I was shocked and immediately shut down his advances, reminding him that Sarah was my best friend and that his behavior was completely unacceptable. I felt incredibly uncomfortable and knew I had to do something to protect my friendship with Sarah.

I decided to cut off all contact with Matt and told him that I couldn't be friends with someone who disrespected both Sarah and me in such a way. Sarah later found out about Matt's advances and my decision to end our friendship.

She confronted me, asking why I had cut off Matt without explanation. I struggled with whether to tell her the truth about his advances or to keep it to myself to avoid causing more drama.

Now, Sarah is upset with me for ending my friendship with Matt and not giving him a chance to explain himself.

I feel torn between loyalty to my best friend and my own discomfort with Matt's behavior. So AITA?

The Gray Area of Loyalty

This situation really highlights the gray area of loyalty in friendships. The OP's decision to date Matt, Sarah's ex, right after their breakup raises questions about where one’s loyalty should lie. On one hand, it seems natural to want to explore new romantic possibilities, especially if feelings are mutual. On the other hand, the OP’s choice inevitably feels like a betrayal to Sarah, who likely still has emotions tied to Matt.

It’s a classic case of conflict between personal happiness and loyalty to a friend. Readers can easily empathize with both sides, which is why this story has sparked such intense debate.

That first flirt shift, from breakup comfort to “I want you,” is what made OP’s gut go off like a smoke alarm around Sarah’s ex, Matt.

Why Timing Matters

The timing in this love triangle plays a critical role in the unfolding drama. Matt and Sarah's breakup was recent, which makes the OP's actions feel even more complicated.

This nuance contributes to the conversation; readers are torn between supporting the OP's right to pursue happiness and acknowledging Sarah's potential heartbreak. It’s a situation that many can relate to, making it a hot topic for discussion.

After Matt confessed his feelings, OP didn’t just set boundaries, she went nuclear by cutting off all contact with him.

This is like the dinner bombshell where one woman says she dated her best friend’s ex, and told everyone at the table.

The Community Divide

The Reddit thread reveals a fascinating divide among commenters. Some believe the OP acted selfishly, prioritizing her desires over her friendship, while others argue that Sarah should’ve moved on before becoming possessive over Matt. This split reflects a broader societal debate about the nature of relationships and boundaries.

What’s interesting is how quickly people take sides, often projecting their own experiences onto the situation. This speaks to how personal and subjective feelings about loyalty can be, leading to a vibrant discussion that goes beyond just this one scenario.
