Advice please

So my husband and I are pregnant with our second child(due in less than 5 weeks) and we just got our first house in Feb. and we only spent two days in our house alone until he let his family move in without asking me if I was okay with it. Going on 4 months now with them in my house, and in those 4 months my husband has been up with them drinking at all odds of the night, he completely ignores me unless he wants to have sex. He hasn't slept in our bed in 3 months, his reasoning for not sleeping in our bed is because nothing happens. I feel like why should he get anything, he can't talk to me or even sleep in the same room as me . I feel he only wants me for sex.
