I also am going to say "Hi again Imn."

Basically Dexter has covered a lot of it but I would like to throw my own opinion in here, so yes Dex, I am "Chiming in" hehe.

Imn I think that you need to be honest with him. I see that you have been dating for 2 and a half years and that is an unbelievable amount of time to hold something from someone. I don't think I could do that even if I tried to, I am too easy in being figured out I guess, I give it all away in a very small time frame. I think that if you have been dating that long that he has a very good clue about what is wrong with you. People are very intuitive as I have learned recently because one of my oldest friends who I thought had no clue about what I was going throguh actually had a clue and when I was honest with him it just confirmed what he had thought and so it wasn't a huge deal. I agree with Dex that it will only become a bigger and bigger rift between you, much larger than being honest. What is it that you fear him doing if you tell him? If anything I belive that it will bring you closer. If anything negative happens from it I would question this guys character. Anyways. I think honesty is the key and to just suck up all your fears and go for it. I think it will go over easier than you think but it's all about just going for it. Hope this helps. Please get back to us.
