catfish my boyfriend

I've been having doubts about my boyfriend being faithful. So I got a fake number and pretended I was his ex. At first he told her I don't cheat leave me alone, but after a bit he now wants to hangout and just talk he said he has a bra of hers to give back anyways. Then he texted me and told me he was going to hang out with his male friend after work. I moved to a new state with him I have no one to talk about this with I don't know what decision to make where do I go from here please ladies I'm in need of help 😔😪
