Is this a normal relationship are things coming to an end?

[Jenna]

I am 29 and my boyfriend is 31. we have been living together for 2 years. He refuses to have me on his facebook friends list and post no pics of us but most of his friends know we are together. Every other person he meets he adds. secondly he is not very affectionate: when I come home from work he never hugs me or gives me a kiss, in fact he barley kisses me at all unless he wants to have sex. Our sex life is still good he'd have sex every day if I let him. when we go out dancing or to the gym he pretty much leaves me alone untill it's time to leave. Lately he has been wanting to see his 'boys' more snd go clubbin or drinking with them. He also said a few days ago he was never going to marry me which crushed me completly. I am really stressin over this and need some unbiased answers.
