I completely agree with all Popcornbird and Samantha Puppy had to say - (and Popcornbird I thought you were MUCH older than 18, your age certainly doesn't show in your threads!). I always had urges to go out every weekend when I was 14, 15, 16, 17 and meet boys, go to parties etc, and I never had a proper boyfriend the whole time I was at school. I didn't think I would ever find a guy because I believed I was unattractive, weird and I didn't know what to do when I was around guys, although I could be an excellent FRIEND.
Matt came along when I was 19, I basically moved in with him the first day we met (I didn't have a bed at the flat I was living in, I was sleeping on the couch, so he offered me his bed - and he would sleep on the couch), and I never left! He is my *first* (if you get what I mean) and only, and we are completely best friends. It took a long time for us to truly trust each other, he had been badly bitten by a previous girlfriend - she dumped him saying that he wasn't tall enough - at least that's to my knowledge anyway. He's about 5'3" and I'm about 5'7".
Anyway we're now very happy together in our three bedroom rental place all to ourselves and our beautiful pets. I'm now 23 and he is 25, we've been together for almost 4 1/2 years, and there are still things that we discover about each other, which is cool because it gives you something to figure out all the time as we are both evolving as individuals, and in our relationship.
At times I do feel that being in such a committed relationship is a pain in the bum, I'd love to just go out and do my own thing, with no consequences and no one to report to. I may still be living at home, because I feel tied to living in this house and having this relationship, but then I look at what I do have and I couldn't imagine leaving it all behind. I certainly couldn't imagine destroying this relationship by doing something stupid like being unfaithful.

Luckily, Matt comes from good stock - his dad is the best man in the world! (And hopefully will be walking me down the aisle one day!)
We will get married one day - I thought it would be nice to be married when I'm 24 because that sounded like a cool age, but now I'm 23 1/2 so I don't think that will happen for me! I just can't wait for the day I do get married because not only will I be a 'Princess' (yay, I've always wanted to be a princess!), but I will be able to have dogs and maybe more cats, who knows! Furry additions to the family! I can't wait to get a couple of dogs!

Sorry for the blah blah but it's a nerve of mine you've tweaked so I thought I would contribute.
You will be so excited when you do finally get married, I hope that when the day comes, it will be better than you dream it to be!
