I am trying to figure out a way to cheer my husband up. Heres a little background

He's a marine, his co-workers are against him because he's a hard worker, he's been having back to back blinding migraines, his the only one working, in school, I'm pregnant, and he has taken on all the household responsibilities, and my son his step son told him he doesn't like him because my son isnt use to male authority but it hurt his feelings. And my mood swings aren't helping. He's afraid to have sex with me because he's afraid to hurt the baby. Which I already explained it's not going to happen.
