I'm having trouble trusting my boyfriend... We've been together almost 3 months. He's wonderful, and everything I've asked for. But every boyfriend I've had has cheated on me. And suddenly, he's talking to a good friend of his (who I have never heard of before, and I've met all his very close friends,) and is trying to break plans with me to go hang with her. I've seen her, and she is pretty much everything he has described in his "perfect girl". I don't know what to do. I talked to him about it, but he keeps saying he's not going to cheat, and he would never do that to me. But I just can't seem to trust him. It just little things he does, like, he got mad at me for texting my guy friends when we were hanging out, so, I stopped, saying I was busy and would text back later... Now he won't stop texting her... I'm worried, and I don't know what to do... Can anyone help me?
