I've been with my ex for almost 6 months. Everything is perfect in our relationship, I honestly couldn't ask for more in a guy. He's really good to me. But for some reason, the past few month of our relationship I couln'd able to understand him about the way he is and then we are split. I just don't understand why I can't stop thinking about him. I have to hear from him every once in a while to stay content, which gets me in trouble with my current boyfriend. What should I do? I can't keeping going about things this way. I dont want to hurt myself or anyone else
