A little about myself first, I am 18 and just graduated from high school. I met my current boyfriend at the beginning of January and we started going out on Valentines Day. He treats me how I should be treated and we get along very well, for the most part. The other day I did find out that he asked his ex-girlfriend (that happens to be pregnant by him-don't worry we didn't even know each other when that happened) to pay his car payment. And he told me that his step-mom was going to pay it. I haven't really had the best guy-figures in my life. I don't see my father, neither do I talk to him. Almost every guy that I've looked up to in my life has cheated, and it puts a damper in my trust for guys. So naturally when I find out that he lied to me about who was paying his car payment I check into it a bit more and find out they have been texting too much. I do know most of the night texts were when they were fighting because I was next to him. But, I did confront him about it, and he told me that he does check in with her once or twice a week to see how she is doing since she's pregnant with his kid. I understand somewhat about the situation and that they still need to talk, all I ask him is that he is honest with me. He told me he didn't think it was a big deal that he checks up on her, and he did apologize for lying about his car payment. (which we have money put back for-so I have NO idea why he needed someone to pay it anyway). I just want some advice on the situation and if I over-reacted. And I want some advice on how to trust him more. He hasn't done anything to not make me trust him besides the car thing, and the story he told me about texting is the same story his ex told me, because I called her.
Please help me!
