I can’t afford therapy so that’s not an option.

Before me and my SO got together I was in a relationship with someone for 3 years who hid a whole double life from me ( other girlfriends, lied about his job etc ) now that I’m with someone else I’m constantly in a state of paranoia that he will do the same thing to me although he’s never gave me a reason not to trust him and that results in me constantly asking if he’s hiding anything, if we’re okay etc. I can tell it’s starting to wear him down but I don’t know how to stop this behavior. It’s gotten to the point that I’m asking daily if he loves me or if he’s hiding something and it’s not fair to him. Help.
