What should I do about my boyfriend?

I met my bf in August 2008. He was a friend of a friend, and i kind of knew him through volleyball. Anyways, we were in a class together (i was in 5th year, he was in 6th year) and in January 2009, we started going out.

This is the tricky part...he went to a party one Saturday night, a few weeks into our relationship. At school on Monday, I heard he'd slept with a girl at the party - I was devastated. I dumped him basically as soon as I heard..by text. He didn't know that I knew about the girl though - I just told him that I thought we'd be better as friends..

Things were really awkward for a while - he could barely look at me, ket alone speak to me. He still hadn't told me what had happened with this girl. My friend (also his friend) eventually convinced him to tell me. So, one night, he texted me and told me that at this party he'd kissed this girl - just kissed. I told him that I'd heard, and thats why i'd dumped him. So i told him i wanted to be friends, but that he was a real ****

Gradually, we began texting again, and started going out again a month or so later. We've been going out since then (About April last year) without any major problems.

However. His ex is doing her best to make me feel paranoid. They went out for a while (i don't know how long, he doesn't like to say, and i don't like to ask) but I know he lost his virginity to her. They split up in 2007, and remain friends, which i'd be fine with if she didn't obviously still like him. She constantly texts him, facebooks him etc. Thing is, he usually texts back. I don't really want to say anything to him, butits really bugging me!!

I tell myself I trust him, but this party incident is at the back of my mind, and I worry about his ex stealing him.

I love my boyfriend, but sometimes i feel inferior to his ex. So what should I do? Confront him - tell him I don't like his clingy ex (and risk sounding clingy myself) or leave it and hope that she moves on?

Advice much appreciated!!!
