My boyfriend is a jerk, or am I just too sensitive?

You're both under a lot of stress. He probably feels his work is not appreciated, and vice-versa for you. Say kind words to him, and once your daughter sleeps tell him that he's a good man but that sometimes you feel hurt, and ask him what hurts him. Remember to be affectionate--that does not mean going all the way, but when our first son was born and we had a lot of stress, a nice HJ would make me more much more willing to swallow my own frustration, hear her out, and want to make it work. We're married for 24 years now.
