How do you build trust for the good relationship

Ashley

Basically I’ve had more relationships than my current partner and well all of them didn’t go good at all. I’ve had two bad ones that aimed at my jealously and trust. Now that I’m in this relationship everything was good and then he moved in with me I’m a curious person so I looked through his messages and I didn’t find anything since he does talk to other girls but he doesn’t respond at all. But still I am jealous that he still gets the messages he’s like too nice to say hey don’t talk to me anymore. I’ve even stopped him from talking to one girl who was an ex but he kept it all business. I know I need to give him space and he completely trusts me so I don’t know what to do. I do love him and he loves me and we’re to be engaged this year at least I hope. Should I just need to learn to chill?
