I’m hurt

So my husband and I have been together for 4 years. When we were just dating he did thoughtful things for holidays, flowers for birthdays, sweet random cards, etc. He just always acknowledged special days. Now that we’ve been married for almost 2 years and have an 8 month old he does none of this. For Mother’s Day, my FIRST Mother’s Day he did nothing. He got me a card but after the fact that I told him it hurt my feelings that he did nothing. Well his birthday and Father’s Day came around and we are broke but I bought him a pair of shoes and got him a card and signed our sons name. Well yesterday was my birthday. He once again did nothing for me. I am hurt by this. Yes, I stay home with my son so we’ve sacrificed financially but a card cost so little but would have made my wife and momma heart happy. We were even supposed to go eat yesterday, just somewhere cheap but instead he tells me he has to go to work so I go shopping with my mom for my son and unborn son. I get home and he hasn’t gone to work he’s just mowing the yard. Please let me know if I’m being petty or if I should approach him about it. I just don’t know why he doesnt care that I feel special on special days.
