How to get my baby daddy back

So y’all really about to hate me ....so I broke up with my baby daddy about a year ago he cheated on me . About 8 months ago we started hooking up again he then started to tell me he really want to get back with me . He later in found out he got the girl pregnant so ended up staying with her . He always tell me he know she’s not right for him and gets him into bad situations.

He asked me if I would wait for him and I didn’t give him an answer bc I didn’t want to break any promises . I ended up dating two other guys and they just weren’t right for me , and I still love my baby daddy .

I known him since I was in high school and we are each other first love. He still tells me all the time he still loves me but knows he can’t take care of me like he wants to . I know it sounds like all BS. But he told his mom and dad and best friend how he feels about me and I do believe him.

How do I get him out of the relationship hes in rn
