Am I depressed?

I didn't want to get out of bed today to avoid seeing my man. He hasn't wanted to have sex lately and I'm sick of it. I've tried everything and he just not in the mood. But I will admit I'm not in the mood either. It just upsets me how he can stay at home and not do anything while I come home and try to seduce him? So I slept until he left for work. It's easy for me to do it because he works at 3 and I work at 9pm. Is it okay to avoid him sometimes to prove a point? Or am I about to be on my period and just really bitchy?
