Family really judging my new job?

So I was a Program Director for a top 3 Tech Company.. I just had a baby.. and as a director managing a large team I found I just needed a break from the stress.. so.. I decided to start a digital design, PR and Marketing business with my sister.. well we are 6 months into it and I am making more money than I’ve ever made in my life.. we have clients out the wazoo.. I’m busier and happier than ever, able to afford daycare and spend days with my daughter when I please.. my husband who was an attorney has been able to take a leave of absence from work and I’ve been able to afford our 3k a month mortgage plus all the luxuries we could ever want. Just the other night I told him I felt like I had everything I ever wanted.. Life is great. Well my husband let the word slip I quit my job at the top tech company to his family and “gasp” .... now the whole family knows and they are asking questions about why I quit.. saying it was a poor choice..eek calling it unstable etc..saying starting your own business is dangerous financially.. my father in law has even said “shit that was so dumb, I have no idea what she even does” to the entire family and just today we left a family function with it being the entire topic of discussion about how risky and unstable of a decision it was..I told them the name of my business .. got weird looks.. just really negative reaction overall... I’m trying to understand why they would react that way.. is it jealousy ? Are they just trying to get to me? Maybe it provoked an insecurity in them? ...it would’ve been so nice to hear something like “that is so brave, we are so proud of you!”... but who knows... stinks..and am not even wanting to face them for a while.. I feel embarrassed truthfully..any advice? Just keep on trucking on?
