AITAH if I cut off my ex ?

My ex and I weee together for 6 yrs and I broke up with him a month ago. I loved him but the relationship wasn’t going anywhere and he had a lot of financial issues he needed to sort out plus I hated that he saw his friends more than me because we lived far and couldn’t move in because he was broke basically

Anyways I ended things, the plan was to stop communicating but he was very persistent that he wants to stay friends. I gave in and honestly I didn’t want to let go yet plus he promised he will not be dating until he gets things in order for himself and then his plan is to win me back if I’m open to it (I also said I’m not planning to date for a while)

Well he’s been telling me lately about going out every weekend since the breakup til 2 or 3 am partying with his new friends, how they got the cops called on them, he’s been getting wasted, and how he is taking the girls home after the parties (to their house but he swears nothing has gone down) and he is telling me how one of his new female friends from work is buying him a ticket to an edm concert and how it would be rude if he doesn’t go with her.

Anyways meanwhile I have been isolating and working on myself working out, focusing on work, school, etc. I’m in a position where I want to buy a house soon and am able to do so

I’m feeling really upset hearing that he is out every weekend, drunk driving, going out with other women but he denies it’s anything more than friends, but I still care about him and I promised we would meet a few times a month to check in with each other

But. Now im starting to feel a lot of animosity and I’m upset hearing about his weekends.

I’m not sure what to do, I still love him and care about him but I’m not sure I can handle it (feeling like he moved on so quick) meanwhile I know I won’t date for at least 6 months
