I am so heartbroken

[Brokenheartedman12]

Maybe I’m being overly dramatic, but usually my gut is right. I have been friends with a female for 3 years. I never once thought of her anymore than a sister. I never flirted with her or even thought to ask her out. Wed talk everyday, and I started including her to come out with my ex fiance. They got close and I was happy since my ex didn’t have many friends. Since my break up I notice this girl has also been distant and I think I found out why.  She had a brother and I feel my ex and her brother might be talking. I don’t have any proof but I know they’ve been all hanging out and my friend does not call or text me like she use to. I am truly heart broken but I feel terrible right now.

It's hard when we still have an affinity for our exes and they move on.

Before you convince yourself of the worst-case scenario, I'd talk to your friend. Not to accuse her of anything, but to maybe get a gauge on where she's at instead of trying to connect dots that you don't yet know are connected.

And if it does turn out your ex is interested in her brother, as painful as that would be, it's probably better to know than to spend weeks imagining every possible scenario. Maybe your friend just doesn't want to get in the middle of a messy situation!

I had a best friend for 20+ years and she slowly distanced herself from me, I have no clue why, I even asked if everything is okay and she said yes. Long story short, she became more and more distant and was not there during a very difficult time for me. I eventually withdrew altogether and cut her out of my life.

You may have to do the same, especially if her brother is now dating your ex. It would be too painful for you to stay close while constantly being reminded of your past relationship. If she's checked out, you can't carry it on your own.

The other scenario is that maybe your "friend" may have developed feelings for you at some point. You said you always saw her like a sister, but that doesn't necessarily mean she saw you the same way. Watching you with your fiancée, then seeing the relationship end, and now potentially seeing your ex become close to her brother and it bothering you could be creating an awkward situation for her. That's only one possibility, though and not something you should assume.

I think you should reach out to your friend with something basic like “it’s been a while. How has it been”. Your friend might just think it’s a really awkward situation.
