Long distance relationship.

I'm dating someone from USA and I live in the United Kingdom. We've been dating since November 2008.  He sends me pictures of him and we've been on webcam to each other a lot but he says he loves me and stuff but sometimes I think he's lying just to make me happy and believe me he does make me happy. 

He tells me one day he wants to marry me and meet me one time. We have loads of things in common and he's 2 weeks older then me.  But sometimes I think is he worth it? 

I do love him. But he told me he used to be a player at school till he met me, he told me he stopped once he met me, but I'm not sure whether to believe him, I do trust him and he trusts me. 

I feel like I should call off the relationship but we've split up once and that was 3 days we got together and he wanted me back. 

He's probably treated me better then any guy I've been with but I feel like he deserves someone better and I told him that but he said he deserves me. 

Urgh -sighs-.
