AIBU? Ex boyfriend?

[user1497020183]

An ex of mine started going out with one a girl who I was best friends with while I was with him, and we were still friends when they got together (this is 5/6 years ago) I thought I would be able to handle it at the time but realised I couldn't and told her that I thought it would be best that we weren't friends.
I been with my current partner 5 years and my life has moved on. She gave her congratulations when I recently had a baby (hadn't spoken to her for 5 years previously) I thanked her and left it at that. She tried to follow me on instagam and I accepted but I haven't followed her back as I don't need to see photos of her with my ex.. I don't want to look like I'm not over it or holding a grude cos of course I am and I don't hold a grudge anymore, but nevertheless I don't need to see her with my ex in my newsfeed. AIBU?

YANBU. She's insensitive for dating an ex of a friend. You just don't do that to your friends

I wouldn't like this either OP. How long were you in a relationship with your ex for and how long was it left after you split up before they started a relationship? Not that it really matters

Just under 2.5 years, and I think it's was 6-12 months after we split up. She was the first person who helped 'pick me up' so to speak when we broke up.

Ynbu, but it will look like your still not over it.
Ultimately do you really care? Your life's moved on and I'm guessing your happy with a new baby. If I was you I wouldn't of accepted her request in insta.

apart from the baby part I could have written this and I'm definitely over my emotionally abusive ex
Together 5 years. Broke up, decent friendship with her that ran long before getting with him. She was actually with me when he first asked me out and went through all this initial stuff with me which just makes me think ew now. And yeah a year or so later she starts lying about it until a facebook pic reveals it all and turns out I'm pretty much the last one to know, which ill be honest hurt a bit.

I then got accused of making HER feel uncomfortable at a bbq for not being very sociable with them deleted and blocked both, can't be dealing with it

YANBU!
I don't think it's so much about bring over your ex but more about the deceit from her.
She was meant to be your friend!
Friends do not ever go out with their friends exes.
She got your left overs. She's welcome to him.
Non the less she was a shit friend and can't be trusted.

YANBU

It's how you feel and I'd feel the same too, but I think you probably are being unreasonable for feeling it. He was a free agent when he got together with her, as was she. They didn't cheat on you. They were consenting adults and they had a right to start a relationship if they wanted to, they didn't require your permission.

That being said, I entirely understand why you might feel betrayed (I would too). You have no obligation to remain friends with someone, follow them on social media or restart a friendship just because they want to. She is being unreasonable if that's what she expects. I'd definitely not want to see the photos either (not because I still loved the ex but because I'd feel betrayed by my friend).
