Not in the mood...

Lately my husband hasn't been in the mood for sex... well I shouldn't say lately this has been going on for over 6 months now. Everything I want to he doesn't. Sometimes just don't give him a choice but then he just pushes me away and rolls over.. IV tried everything I can think of to get him in the mood but nothing works. I don't know wat else to do... it's really been affect in my ego and he doesn't seem to care
