To be uncomfortable with my baby's dad trying to get with his best friend's ex?

[Amytheflag]

As the title says,

Am I being unreasonable to be uncomfortable with my baby's dad trying to get with his best friend's ex?

We've only been split up a month (my choice due to abuse) and this girl was with his friend for three years. I don't think that I feel jealous, just feel weird as this is someone we used to double date with so I know her quite well plus this girl is his friend's only serious ex. It feels extra uncomfortable too as none of us have spoken to her for over a year (since she went a bit weird and kept harassing us to try and get in touch with the best friend after they broke up) so he's specifically hunted her down to try to get with her which is making me doubt everything ever lol. When we broke up, he said to me he would never speak to me again if I got with one of his friends (not that I would) and that friends' exes are off limits but here he is trying to do that exact thing.

So. AIBU to feel a bit uncomfortable about this?

yabu. If you were upset he has moved on so quickly I would kind of get it.

Its between him, his friend and her.

I feel sorry for the girl who is probably being targeted by him simply to get back at you, and also the fact that she is likely to be his next victim of abuse too.

YABU

I would feel very sorry for the girl, but I wouldn't feel uncomfortable on her ex partners behalf.

Also when you split with someone they don't get to make the rules about who you can and can't date I'd have told him to fuck himself if I were you.

Yanbu to feel uncomfortable if you suspect your ex is doing this just to score points or because he might have had his eye on her as your relationship fell apart and moved in quickly as soon as she and best friend split.

Beyond feeling uncomfortable yabu if you try and meddle or have any influence on either your ex or the girl.

Don't let your ex dictate who you date, either.

Thanks everyone for the replies :) I think I'm right to feel uncomfortable since I used to be friends with her so its a bit close to home but I agree that I should keep my opinion to myself about it because that's true what you all said about it isn't his business who I date so I guess it's not mine who he dates. I won't be letting him tell me who I can be with after this though that's for sure!
