Is this wrong of me?

So long story short (this is gonna sound bad) I dumped my fiance of 2 years for another girl and out of no where o started gaming out with her and my mom but sometimes just me and her and I just recently added her to my PS4 friends list. Is this wrong of me if I'm in a new relationship? We have no kids together or no reason to stay In touch but I love gaming with her for some reason... also she's the only girl I dated that my mom likes so she stays in touch with me mom.. should I stop gaming with her?
