Hey ladies

A while back I broke up with my long distance ex because I didn’t feel appreciated or loved like I should. He’s now back in town and we had a talk. I told him what was what and he said he wants to work on himself and make us work. I’m so conflicted. I have deep feelings for him but I’m also scared of getting hurt again. We’ve been a thing for almost 3 years and this isn’t the first time. Any thoughts on what I should do?
