Whats going through my mind?

Daves been the love of my life. I've been with him for 8 months which has been great. But twice know I have cheated on him. Once was with a 19 year old guy called Luke, who I think I had strong feelings for but let it go. Never seen him since. Then three weeks ago, with Matt, a 23 year old who works with him at my job. We kissed and it was so good. Better kisser then anyone I've ever kissed. I shoudn't be saying this. Its bad, but since all this. I've been thinking since i'm only 17(and so is Dave) that maybe I'm not ready for such a serious relationship. I'm young and the temption is always there. I want to see life and experience it, live life to the fullest and not be stuck in a relationship all my life. And Dave is always going on about moving in together, marriage, kids and I can't help but think. I'm not ready. I love him, but why? Why do I love him? It used to feel so good being with him, him being my first and everything, but I saw him the other day and couldn't care less about sex. I don't care if I see him next week, and its upsetting, to finally see that this young love is fading. He doesnt see it, but I do. He loves me more, I can tell. But with his life being so sad and upseting, I think it would so hurt him if I broke up with him. I'll even see him at College everyday.

And Matt. So goodlooking, nice, I can talk to him, funny, flirty. Great guy, we get on so well and he really doesnt push you into anything you dont want to do, hes finds me respectable because I didn't go home with him that night we kissed. But I can't help but think of him.

What shall I do?

Thanks for the advice. Its making me think more, not just what my work friends are saying. I work with mostly guys, which is frustrating and they keep telling me to dump him. But they don't have the best advice, they have nothing more to say, than, how much they want me.

I do want to live my life, do what I want to do, but yet, I feel like, this isn't going anywhere. Don't get me wrong, the past 8 months have been great, he made me happy, laugh and cry and see life a little more. But I want more in life.

Being where I am know, has made me realise that I fancy still other guys and how much I would love to flirt and kiss him, and which shows I'm not ready for this relationship. Being single for a while and not jumping straight into another relationship is what I think would be the best option for me. Seeing and meeting new people.

Daves got to realise, that I'm a pretty girl(not being big headed) and that alot of guys fancy me. Matt for example, Ben. Dan, and well, its hard to resist their charms and think, Wait. I've got a boyfriend.

I'm just going to see what happens. If I keep on cheating, then I know, I'm not ready, and well. Then it comes the "we need to talk" conversation.

Thanks
