sex so bad you cried

So me and my husband been married for almost 6 years, we have a baby girl who is about to 1... well our sex life is almost nonexistent!!! Adult time maybe 1-2 times a month...... our relationship is like being roommates that share a bed..
I just don't know what to do last time we had sex, I half way reached climax but he didn't, we just both gave up. He walked out the room with out a word and I went to the bathroom to cry.... WHAT TO DO:(
He works away for 14 days and comes home for 14..... in which is tomorrow.
