Vent & question

So let me know if this is a legit issue or just hormones!! My boyfriend has a son already and I just feel like he has checked out of this pregnancy. I have done everything except build the dresser for the baby room. He works Saturday's and we have his son every other weekend. Well this weekend we don't have his son and he has Saturday off but instead of helping me he went fishing. I'm so overwhelmed just because I haven't been working and have had to do everything in this house with no help. I just want him to help out a little- I've asked him to do the dishes for 3 weeks now (different dishes) and still nothing. The only thing he does is take the garbage out and I have to ask him to do that. He stayed the night at his parents last night while they are out of town to watch the house but didn't even want to stop by to see me today. I just don't get it! So.. Am I just hormonal or do I have a reason to be upset??
