Should I see a therapist?

In a relationship, I can get extremely jealous, I get mad at the tiniest things, I’m impatient, So what is wrong with me? The biggest thing about me, is that I can get very very jealous. For example, I’m talking to this guy and I noticed he’s following a funny page on Instagram but their profile pic is a girls ass... and I got mad. I don’t know why but I’m terrified of getting cheated on again and I don’t want the guy I’m talking to, to even see girls like that.

I hate so much that I’m like this, and please don’t be rude because I’m already putting myself down. Just want some guidance or some kind of help because I wanna be better I wanna not worry constantly about getting cheated on when I’m in a relationship I feel trapped because of it. I just can’t trust anyone.
