I dont know what to do!?

Sorry about the ESSAY but I want you to know the background information before you advise. :)

Im 17 and he is 18!

I have been in a relationship with my boyfriend for almost 9 months. When we first got together I was so happy, I was with the guy that I had fallen for!

I was literally the happiest person on the planet!

when we first got together things were going great! I introduced him to my friends (Who kind of knew him anyway!) and to my parents and Vice Versa.

We both go to the same college and on a tuesday we teach a lesson together. He takes on the role of the teacher and I the role of the Teaching Aid. When we were in the lesson he started to boss me around and kind of try and tell me he was boss!

This did not go down well!!, He knew I didn't like this and as a result we pretty much ignored each other.

We havent had sex yet but that's another story (He wants to, I'm not ready; however we have done everything else...)

Things have been strange for a little while, He keeps asking me over to his but I know that what he wants to do is have sex and that's not what I want to do at the moment. I have started to get feeling for someone else, someone I know I can never have. I would never tell this person about these feelings but none the less I cant stop thinking about him.

When i'm with with my boyfriend now things just feel a little wierd, and I think he feels this too. (Although im not totally sure about this)

It used to feel just normal, I couldn't wait to see him and spend time with him, we would have a laugh and it was exciting. He was kind of "Posh" well spoken, Knew what he wanted in life, Has a great relationship with his family, has a job and helps out with stuff at college. (volenteers at the DOE sessions and science stuff)

Myself on the other hand. My parents are seperated, I dont have a very good relationship with my mum or my brother (Who i live with) an excellent relationship with my dad however. I have a job but I dont get on too well with my boss. he seems to pick at everything I do, where as my boyfriend gets on with him really well.

Lately some of the things he does really seems to get on my nerves. I dont look forward to him coming over much any more and sometimes put him off of coming over at all. I like the idea of being with him but I just cant be totally focused on him when my feeling for this other person are making me question the feelings I have for my boyfriend.

There are some things about him that really wind me up. E.g. He has a wierd laugh and acts quite gay sometimes (Which is strange because I know for deffinate 100000% sure he is not!) He imbarrases me quite a lot of the time without intending to and just generally belittles me, makes me feel stupid sometimes. as well as never complementing me or trying to make me feel good. Lastly he is quite selfish and always puts himself and what he wants first before me, Its okay sometimes but ALL OF THE TIME, gets on my nerves. especially after i pretty much consider him in everything that involves him or the plans we have made.

We have a friends joint birthday party on saturday night that we have to go to but he wants me to stay at his. I feel ready for sex now but the feelings I have for someone else are making not want to do it with him.

I think we need to go an a non contact break for maybe 2 weeks (not break up) and was going to tell him on wednesday or thursday. However I dont want there to be an atmosphere at the party as we are all sitting down for a meal with a group of friends who are all mutual friends of ours. also all the people who are going are in a relationship and there partners are going. Its 5 couples. myself and my boyfriend and 5 other couples.

I really dont know what to do. Please help!!
