Don't Know What to Do.

So my husband works a lot and he is maybe home 1 night out of the week I'm taking care of the baby and taking him to classes and doing my own classes and taking care of the house. Every time I try to talk to him about if we can have us time or go out for a few hrs he gets mad at me for asking. So I have been sleeping in the guest room next to our 3 year olds room so he doesn't have to see me when he comes home I love him I do I just don't even know what to say I feel like my sex life and marriage is over.😞
