Chances of getting my ex back?

It's a long story so here's the bullet point version: • ex gf and I broke up and she has a new bf (2 months now) • been trying to get her back since the beginning, at first she didn't care • I changed how I tried to get her back by focusing on attraction instead of being sad • something happened last month and since then we have been having an affair. Both physical and emotional • She gets jealous of other girls I'm talking to so now I dropped them all • She asked me if I love her, I said yes. Asked her back and she said maybe (this is better than last week when she said no) • Told my therapist, who is actually talking to both of us, and asked if she is playing mind games and therapist says she is scared not playing mind games Yes I know we shouldn't be having an affair. I don't need to hear anything negative about that. Because I also know we are meant to be together and if there's a chance I want to give it my all. Sex is a type of love language we share (it is high on both our relationship/love priority list). But I'm always on edge and wondering if anyone has any insight on what you think our chances of getting back together are. If you have been in this situation let me know please.
