baby shower

I am having a bit of an issue with organizing my baby shower. My family and my husband's family doesn't get along to well due to the fact that his cousin and my sister dated for a while and he used to beat on her. 2 years later my sister finally ended the relationship but ended up calling the cops. This ended in a very big family drama with both sides. Now both sides of the family is talking bout baby shower ideas and who is going. But in order for this to happen we will need two separate baby showers exceeding my budget. If we make one big party we are afraid of a big chaos. My mom is willing to do the party at her house but just my side of the family. I honestly feel that if both families can't come to one party for my baby I don't need to have one period. cost of two parties will be roughly 1,500$ we both have a huge family our guest list is nearly 150 people. I feel a baby shower is for me and baby to be showered with gifts and me not spend a dime. But if I have to spend over 1k $ I feel I just shouldn't do one and I will buy my baby all she needs. My mother feels very terrible for this but it's not her fault. Am I wrong for this? I am currently renting an apartment so I can't fit 150 people in my place.
