Am I just lonely??

Over a year ago my fiancee and I broke up. It hurt like heck cuz he was the first guy who ever really treated me decently. He was my best friend. He just wasn't husband material & he isn't ready to become one either so it turns out.

Anyways, it's been awhile so I am doing immensely better. I'm even to the point of realizing he isn't going to make the changes I would need in a man, & he's proven that I'm not the only woman he could ever love. so I'm not looking to get back together with him anymore.

However, now a previous ex is back in my life... And he didn't treat me so good the first time around. However he's made changes & says he isn't proud of what he was & wants to become a better person.

I know I want to spend more time with him, cuz of course I'm interested.... But I don't know if I'm really interested in him or if I'm just trying to fill my void of loneliness... What do I do? Do I cut contact??
