<human>: Give me the gist of the text in a nutshell

I used to be in a bunch of toxic relationships in high school. I had a girl cheat on me, and a girl I used to date broke up with my because I was so possessive and overbearing. And I'm so fucking tired of being that way because it's destroying my relationship that I have right now.

My current relationship has been around for about 3 months, and we have been spending a bunch of time together because we live so close in the dorms that we're currently living in. Her name is Cadence. 

Cadence never dated or kissed anyone before me partially due to her moral values and also because of her strict parents. She's always been very popular with a bunch of guys but she's never given any of them a chance except me. 

Although I really want this to work, it seems like the trust issues that have arrised from my previous relationships are beginning to surface from the deeper parts of my personality. And even I think that i'm going borderline insane. Let me write some bullet points out for you. 

1. I get really scared and upset when she cancels on me last minute. (I know this isn't okay.)
2. I'm really protective about her with other guys. I know for a fact that she gets hit on often so that scares me too. (I know that isn't okay either.)
3. We haven't had sex yet, and whenever I ask or try something intimate, I always feel bad later on because I know she's a bit uncomfortable with anything before 2nd base. 

I really want to make this work because she's been very patient with me and both of us have worked and fallen too hard on this relationship for it to fall apart because of my trust issues. 

How do I deal with this overbearing and protective feeling I get?

Thank you all so much!
<bot>: I'm very happy with my Girlfriend right now who gets hit on by a bunch of guys. I have trust issues from previous relationships and I've become overbearing and overprotective because of it.
