I (35M) separated from my wife (34F) in August. Our marriage had issues. Things were really good at the beginning, but I cheated on her with a colleague. She told me she forgave me and that we would not bring this up ever again, but after that, things were never quite the same. She became more distant, stopped putting the same effort into the relationship; she stopped cooking for me, wasn’t affectionate like before, and often shut me out emotionally. She became really whiny when we had a neighbor blasting the music in his apartment (it was daylight so it was fine) and she confronted him about it, and this was the last straw for me. The love just didn’t feel mutual anymore.

After the breakup, I quickly started seeing my current girlfriend (29F). At first, we argued a lot and I wasn’t taking the relationship too seriously. During that time, I had a few moments of weakness and kissed my ex-wife and we talked often since.

Now things with my girlfriend are going great. She’s been incredibly loyal, patient, and has fought hard to keep us together. I want to fully commit to her.

My ex-wife and I are finalizing our divorce. I suggested a dinner between me, my girlfriend, and my ex, so we could all move forward respectfully. My ex refused and said she would only meet with me alone. She claimed it was out of respect for my girlfriend, saying she didn’t want to trigger any jealousy or tension, but it came off sarcastic, like she was subtly mocking her for being insecure (I told her my girlfriend is very jealous of her and I caught her stalking my ex wife on social media).

So I told her forget it, don’t want to have dinner if she can’t respect where I am now and who I’m with. She got mad and said she was just trying to avoid unnecessary drama. I really wanted to be respectful and keep a good relationship with my ex. I’m not talking to my ex wife again except for divorce papers. AITA?

EDIT: I’ve seen a lot of backlash in the comments and I wanted to add that after the divorce, I offered my support to my ex-wife and always checked in to see if she was okay. I helped her move into her new apartment after the breakup. I even told my girlfriend that my ex will always be important to me, but we didn’t work out as a couple. Two months ago, my ex lost her job and I took her out for dinner and told her she could move into my apartment if she had nowhere to go. So despite everything, I have been caring and respectful toward her.
