I've had this on and off thing with someone for a long time. Maybe over a year now. He has left me so many times I have a hard time trusting him this time. Every time he says he wants only me. And this time he says he's ready to drop everything to make things work. But I have such a hard time believing that. I want to trust him, and I want things to work. Because I know if I lose him I'll lose a deep connection that I'll never find with anyone else again. But I just can't shake my fear and suspicion. I've been trying to use radical acceptance, but I'm just scared. We're currently trying to just stay friends so we can both get better mentally before trying commitment. He says he only wants me but I saw a tweet saying he's been talking to a girl. I'm telling myself over and over that they're just talking but my mind is telling me he's moved on already. I just really want to trust him. And I really want us to work. Can anyone help?
