Second time my husband hasn’t acknowledged Mother’s Day

I gave birth to our daughter a few weeks before Mother’s Day 2017. We were separated at the time but he sent me a huge bouquet of flowers. We got back together after a few months. Last year he didn’t get me flowers or even wish me a happy Mother’s Day but told everyone else. Same thing this year and I’m pregnant with our second child. I waited all day for at least a text from him bc he was working. Nothing. Finally when he got home I heard him talking to his aunt and he wished her a happy Mother’s Day. When he got off the phone I told him happy Mother’s Day to the mother of his children and he said oh yeah happy Mother’s Day and then sat down to watch tv.
