Boyfriend going out

I am fairly new to being an actual adult relationship where I can trust my boyfriend. All my pay boyfriends have cheated or taken my trust for granted.

When my boyfriend goes out I get really bad anxiety and it makes me think of the worst. I am trying to be better and not be like this because he is a good guy and I trust him very much to know he would never cheat or let his friends get him into a bad situation.

I was hoping there was other people that feel this way so I’m not alone? And maybe some could give me ways they’ve dealt with it so I’m not living like this. I want to be better so I’m not worrying all the time and making him feel like I don’t trust him.
