I love my bestfriend.

so, I dated my bestfriend 4 years ago, and stupidly broke up with him.. clearly meaning, I regret it. we’ve dated a couple times since then but it never seems to work out. even though I see that we’ve gone out a couple times since then and it hasn’t worked out.. I still find myself head over heals for him. I don’t know what to do.. he sends off vibes that I’m unable to read. some times I think he still likes me.. and my therapist says it’s very likely considering some of the conversations my friend and I have had. he said to me that “the only thing keeping me from liking you again is the fear of you hurting me like you did before” .. referring to when I broke up with him 4 years ago. he said this to me probably 5 months ago. do you think he still likes me.. or am I just overthinking everything and should attempt to get over him?
