Toxic Inlaws

Me and my husband are currently in the process of purchasing our first home, we have two children one who is turning 3 this year and the other is a month old. We found a house that we absolutely ADORE its move in ready very minimal work that we know of (inspections on thurs) well we are moving about 15 mins away from both of our parents and when they found out my FIL told my husband that we do not care about them and we are selfish for moving “far away” from them. His mother is VERY upset aswell. She continuously asked him if he was sure he could make the payments on the house because he is the only one working due to me being a SAHM this isn’t the first time she’s complained about me not working. I hate seeing my husband upset due to the lack of support he receives from his parents. I currently applied to two jobs because I just want to prove them wrong... advice please....
