Breaking up?

My boyfriend and I almost broke up last night. I understand why he decided to almost break upwith me and I don't blame him. After being treated like complete crap by others guys: being lied to, used, and just discarded like a piece of trash. So, I have a tendency of not believing a lot of the things he tells me. It's hard to believe when he says he loves me, that he won't leave me, and that he loves my body and all my insecurities. It hurts his feelings when I disregard his love towards me and that I pretty much always say I don't believe him. Plus this is something that we always go through where he has to reassure me again and again that he does love me and won't leave me. I know it's tiring for him and I am so sorry about it. I begged him to not leave me but he decided that he hated that I don't believe him. I finally accepted it and call my mom basically balling my eyes out. She told me that I shouldn't cry and that she doesn't blame him for feeling the way he does. She said that I can't just tell him that I don't believe anything he says, but that if he really want to be with me then we'll be together. The call ended and I texted my boyfriend that I understood why he wanted this and that my mom knew about it. He texted me about how he doesn't want to be with anyone else and he won't do anything else with anyone. As the conversation continued, he realized that he couldn't end things. He said that he needs me and leaving me would break his heart. I told him that I would work on my problems by talking to my therapist about it. I really hate the fact that I can't always believe everything he says. I know he loves me and I wouldn't have told my parents about him if I didn't see a future with him. He is so important to me and I know he means nothing but the best. I hope he realizes that I will work on my problems for him and I.
