Should I or shouldn’t I???🤔

Love Love

So I am going to be 33 and I was dating a younger dude. He was my trainer at first, and we ended up have sex....a few times... at first it was just sex. That’s all he wanted and because he was younger, that’s all I wanted. But of course, it blossomed. I wanted more and for a while he didn’t. But he started to develop feelings for me.... we had tried off and on the relationship thing but as I mentioned, it was off and on and we couldn’t make it stick... attitudes, stubbornness, control...all that between the two of us... I’m mean.. he is a cancer and I’m a leo.. 2 controlling signs.... but he delivers in the bedroom and I enjoy how me makes me feel... we decided to give it a try and it was as going well, he even was changing and opening up and until we got into a disagreement and ended up having sex that I didn’t enjoy because I was turned off.. he felt that disconnect and he left me and now he is back telling me that he handled things wrong, he made a mistake, I am his soulmate, he loves me so much, he couldn’t stop thinking about me, he wants me to have his kids and marry him one day.... I miss him but I am skeptical and am not too sure.. I mean I think he is serious but.... what do you guys think??
