Dear Diana,

My boyfriend is really sweet. It took him two months to muster the courage to kiss me. Also when we made Iove, it was beautiful, passionate and really tender. He was everything I could ask for. Now he has changed for the worse and has become distant and has started saying that I'm cheating on him (I'm not!). We make up, settle the argument and then he's back to the same stupidity.

He argues over stupid things and goes for days without calling me. And when he does, he starts behaving like he's checking up on me. I love him every much but he's changed. He says he hasn't but I know he has. I think he's a bit insecure. He's always been the shy type.
