Ladies advice please am I over reacting or I'm in the right!! So my s/O and I have friends who

Invited us to their kids bday party, both on the same day. (TODAY). Well I kinda don't want to go, one because we invited both of them for our gender reveal for our daughter neither of them showed up.. invited them both to our baby shower.. one of them showed up and didn't even bring a gift or a card. (Side note: went to both of his kids baby shower and his sons first bday) The other friend had a baby shower prior to mine and we couldn't make it, because it was my s/O grandmas bday. But we still managed to dropped off her gift and left.. She didn't show up to ours at all. I just feel like they invite us so we can bring gifts, my s/O is so damn generous he likes to give good gifts..and everyone knows that. Just feel their taking advantage of him..and it bothers me. It's not about the gifts honestly, it's about being there... Like he's always there for them. Idk if I'm over reacting because I'm pregnant, it just irritates me.. ps: the one we did manage to give her a gift for her bb shower, has been bugging me all week.. to see if were coming. Ughh annoyed!!
