Jealousy :(

My boyfriend has recently gotten two new girl friends and he’s honest and i trust him. He always makes sure everything’s okay with me and it IS. i just seem to get overly jealous a lot of the time. and i’m not the kind of girlfriend to not let him have friends or anything. They do know about me. and he tells me stories about them all the time and it just hurts me kind of that he laughs and has fun with them. and since i’m in a long distance, it’s hard for me to process because i wish i could be there to do those things with him and make him happy there. Any tips on how to be less of a fuckin psycho??
