He seems depressed all the time and it feels different between us now but he gets happy when it comes to sexual things. Is he losing interest or is something really bothering him or is he just tired? I'm so confused.

You should tlak to him. Please don't make your relationship run on sex... you should sit him down and telll him its deiiferent. Mabey he's going through some things he's just not tellingyou. Oh and remember, don't attack him when your asking him this..

Good luck!

You should just talk to him but no pressure him into talking to you, if you know him well enough you should be able to tell a difference in the way he acts towards your questions... Has anything been brought up about maybe marriage or kids or anything like that?

Thanks for your advices but when I do talk to him he says nothings wrong and he's just moody sometimes.

I guess you should just talk to him and tell him how you feel and how everything has changed and ask what you can do to get what you two had back.
