Thinking about having another baby but not feeling intimate with my hubs

My husband and I agree having another child would be perfect especially for our 2 yr old daughter. We both have siblings and know she would be so happy to have one too. Only problem is we both have crazy schedules and aren't intimate like we used to be. It probably doesn't help that she sleeps with us but that doesn't stop us (We have a guest bedroom we would sneak off to). I think one of the main issues is Im not in the mood because I feel resentment towards him either because he comes home and complains about one thing but doesn't appreciate the ten other things I did. Or he's traveling for work a lot and therefore not helping at home even while I have a tight schedule for both my daughter and me and I don't have close family or friends nearby to help me or just hang out with.  I also think I'm a little depressed and that's not helping either...Any advise would help. Thanks.
