Mother in Law issues

Sonia
so I had my baby shower today and mother in law a couple days before the baby shower called my husband and said I'm sorry I haven't responded to your wife but I wanted to have a separate baby shower for our side of the family instead my husband blew up and said what's wrong with having all the family together his mom said well son I just think it should be this way one from her side and one from our side .. tell me girls who's wrong here??? BTW no one from his side of the family showed up to the baby shower
