Is it normal that i worrying all the time?

Im a 22 year old male and I just recently ended a seven year relationship with a girl (i say recently, we mutually parted and have been for a couple a monthes), who is now probably one of my best friends. I also came out as bi-sexual and have started a new relationship with a man that i have known for over 3 years, but never tried anything with.

Now i think im going crazy cause i constantly feel the need to no what he is up to, i hold back alot from him and i mean ALOT! i try my best not to be clingy as he doesnt like it. Its got to the stage were i find my self getting angry and annoyed and sometimes slightly emotional at the smallest things, like when he doesnt reply to a text, phonecall or a message on facebook. Little things start mounting up and it is making me feel like im crazy inside.

I get envious because his friends are amazing and so accepting, were as mine are just plain stupid. all my friends that i had were brilliant when we went to school with one another, now they either run about taking drugs or stand on street corners drinking, so i dont socialise much with them. He on the otehr hand has a buzzing social life, and its getting me down.

My boyfriend has never really been in a relationship, so he doesnt really no the ups and downs part of it. then there is the silence. its not all the time though, but its annoying. When we first went out it was great, it was eye opening, and dont get me wrong it still is but we both have work so we dont get to see much of each other...couple that with him saying the three words that i never thought i would hear so early in the relationship, and you get a picture of what i mean.

It took me 3 years to say i love you to my ex girlfriend, three! it took him a matter of weeks. Ever since he said it i have completely changed... i have turned into this person i dont want to be, but at the same time i dont want it to stop! i dont want the relationship to end. There was a connection between us from the start though, i found him very attractive, his personality was amazing to boot, i have this thing for like minded individuals! He likes nearly all the same TV shows/music/films and activities that i do, which is a blessing really.

Its amazing not havign to explain what a word means or dumbing myself down just so the person understands exactly what i mean, he has so many good qualities about him that i find myself loving him.

His faults? he snores... thats it.

He is in university, which is an airplane ride away from me but is over in my country for holidays and i visit him alot also. but i cant help but think that i went through things way too soon.. i dont want to end this relationship because of some minor bumps in the road. Could it be that he is not that expierienced with relationships causing the problems? or could it be me... broke inside?

im stuck in this loop of trying to find the reason as to why im so broken, but i cant... im hoping you lot can help me...

thanks.
