Honest Opinions

So I’d like to know how other moms would feel about this situation. I celebrated my son’s birthday today and unfortunately not alot of people showed up and it’s okay. He still had so much fun. Anyhow, his dad did not show up and I come to find out that his wife is pregnant and they had a baby gender reveal today. My baby daddies parents showed up to my son’s party but only stayed for an hour and told me they had to leave because they had to go to another event. So I find out about the party on facebook. My family says that he is wrong because our son is his first born and he should have atleast shown his face to his son’s party. What do you guys think? How would you feel? I’ve decided that 2025 no house party I’m taking my son and I on a trip or something. I feel like my son will be neglected because my baby daddy was never fully hands on when he was a baby and he has clearly shown that his son won’t be as important once his second child comes.
