Relationship help, please....

i’ve been dating this guy for almost 2 years. but we do have some history. we dated one time before for about 1 year.

when we first started dating he was the jealousy type but since last december it’s turned. i’ve been jealous and insecure for nothing. he’s never given me a reason to not trust him.. i feel like i’m holding on to the past and i truly don’t know what to do. today we didn’t fight but we texted. he pretty much said he didn’t want to break up but he didn’t know what he needed. that he felt trapped. i honestly know that i’m causing this and i tell myself i change but i don’t. and i don’t know why.

we talked about a break or just backing up a little and being a little less intense and just be a normal relationship. and i tell myself okay that’s fine, but i know myself and i know i’ll keep testing and bugging him.

how do i STOP, and just be thankful. I need so much help because i’m so scared of losing him..
