ignored on birthday

so my birthday was a few days ago. Not 1 message from any of dh siblings or partners. I always wish them happy birthday and when something is happening like 40th etc. get involved and make a special effort. long story short at Christmas they also excluded us from a joint present to my mil, a gift we actually suggested of family photo. they wanted one of only their kids, that ended up being all of them. I've left our group messages as I'm fed up. husband says he does not know what he will say if they ask anything. Thoughts???
