Resent my husband after delivery

Jess β€’ I`m 28, Mama to Elyse Cecelia 8/8/16πŸŽ€ RIP angel baby 8/27/15πŸ˜‡
Has anyone else felt resentment and hatred towards their significant other after having your baby? It's getting worse and worse everyday and today made it significantly worse. My daughter who is 4 weeks old did not sleep well last night and my husband left at 730 in the morning to go race his car on a drag strip. It is now 615pm and he is still not home. To me this is very inconsiderate, irresponsible and selfish. I have so much anger... Am I blowing this out of proportion?!
