Should I end it?

Ok so let me give you guys a little backstory. So I’ve been on and off with my boyfriend for about 2 going on 3 years. We met my sophomore and his junior year of high school. I was crazy about him, just like every other teen girl in a relationship and he was just ehh. We even decided to stay together while he went to Iowa and then Florida (he switched schools) for college while I was still in high school (we live in Texas). While he was gone I had found out by a random checkup that I had gotten chlamydia from him (we were sexually active when he was home and i’m still not sure where it came from) and we broke up. In my mind the only way he could’ve given me a std was by having sex with someone else off at school. During the time of us being broken up I got a taste of freedom and the single life while he says he thought about me 24/7. So we get back together maybe 4-5 months later and the roles are reversed and he’s crazy about me now. I love him with all my heart but I don’t like the clingy type. I’m a pretty conservative pearson when it comes to my personal business on social media and he wants me to post all kinds of stuff about him on my social media pages. He wants to be together ALL THE TIME like more than a normal couple should and he wanted to become a part of my friend group with all of my girls. Now here’s where it gets messy, with much regret I made a bad decision and was conversating with another guy and he found out. I felt horrible and promised him it would never happen again which it hasn’t. I told him I would gain his trust back and began posting him a little here and there and spent more time with him. He would ask to see my phone and I would give it up immediately no questions asked and let him check it. But the arguments started to get bad when he would question me on silly things and start problems behind unnecessary reasons. After he gave me that std I’ve been afraid to catch another one so when I say no to sex he’ll attempt to pressure me and if i still say no he freaks out on me or stops talking to me for a day or two. He also checked my phone and assumed I was cheating because I said no to sex after he told me he wouldn’t freak out and he trusted me. He goes through my liked tweets on twitter to make sure I didn’t like a guys picture that he doesn’t know. I liked a photo of a guy i know from school that he doesn’t know in a pool, of course without a shirt on because it’s a pool, and he told me it was crossing boundaries and “what did he tell me about liking pictures”. I feel like there’s a new problem every step I take in this relationship and he acts all happy one second then ambushes me with another problem. I love him with all of my heart and I know that no relationship is perfect but should i break up with him to just end this toxic relationship? I going away to college in 4 days and I assume if he can’t trust me now, his head will implode while we’re away at college. He says he trusts me but it’s obvious he doesn’t.
