Should I move on?

My ex broke up with me about two weeks ago, because he was unhappy. But he still talks to me several times a week and
Takes me out on dates, or I guess spends time with me. And yes we are still intimate and he is not pulling out…. I’m not sure why he would leave me and then finish inside of me multiple times… he left me because i gained weight and he’s told me he’s not like attracted to me. But he always ignites sex with me and he has a bonnet all the time around me. we were together for 12 years. So I’m alittle confused and it may be obvious to others but not me at this time. I just want to know like do you guys think there is a chance he will take me back? When I lose the weight? I love this man and it’s very hard for me to let go but I rather let go now before I’m hurt again..
