Friend got with my ex

My friend got with my ex at a party, we weren’t official and it was a while ago but I feel weird about it and girl code?? How do I deal

Slap her Jesus why haven’t you already

think you've just highlighted here why it doesn't matter.

Yeah I get that but partly feel betrayed like she’s taking his side

sides? are you still quarrelling with him?

Do I want a fight tho, also don’t really want him thinking I still care u know

So just leave it or maybe say to her this is making me sort of in compfortable so can you not talk about him to me xx

Did she tell you about it?

I was there

Who cares? What business of yours is it? You're not going out anymore, so you have no say in who they go out with now. If they want to go out with your friend, it's a free country, and there's no such thing as "girl code".
I'm sorry for being blunt about this, I'm just telling it how it is. You can't tell your ex who to go out with, nor can you tell your friend who to go out with. If they want to go out then either ignore it or try and be happy for them. Don't try to **** up their relationship out of spite or anything.

I haven’t that’s exactly why I’ve left them to it and not started a fight, just told her I was upset about it then left it when she didn’t seem to care
