<human>: Provide a brief overview of the text.

So as the title says, my anxiety has been way out of control.
I met my boyfriend, let's call him John in high school. We were in total different social groups. He was a jock, super good looking etc. I on the other hand was not. I was shy and quiet. I had feelings for him, but never acted on them for fear of rejection.

We always dated different people. He moved away got engaged and all that jazz. I also was engaged, my ex and I were together 4 years. He (my ex) was very abusive - physically, sexually, and verbally. He also cheated on me multiple times. Thankfully I got out.

Anyways, a few months ago John and I  reconnected on social media, he asked me to hangout one day. (Which totally surprised me) so we went out and have literally been inseparable ever since.

My problem is, John is still VERY attractive. Whenever we are out other girls are always looking at him. It's weird to me. I get quite annoyed. I guess I'm a jealous person, but considering the crap I've gone through with previous relationships (being cheated on, etc) I don't think that's unreasonable. He says he loves me and only wants me, I'm not sure I can believe him. My anxiety is terribly high. 

Can anyone give me some advice?
