am i in the wrong here?

for background; my husbands grandparents were extremely controlling and verbally/emotionally abusive to him his entire childhood. we met when he was 18, and he slowly started backing off from them. when we got pregnant, we had just got married the previous month and they said horrible things about me. including how im controlling, im baby trapping him, i use him for his money etc. mind you, my husband does not make a lot. i love him but if i was going to use someone for money it would be someone with a better job- and neither of us wanted kids so when i found out i was pregnant, we both strongly considered abortion and eventually. decided against it. my husband has had confrontation anxiety for years and we have been going to therapy together to work through this. thankfully in the process he has also learned to stand up for himself. when he family started acting like this, he made it extremely clear if they were unwilling to accept me and his choices, they would not be part of our life. this is a comment they made today under my facebook post. i have always let my husband handle his family issues, but i feel completely embarrassed they would make a comment like this on my public page where all my friends and family can see. and im angry they are trying tk turn it around on us, on too of taking our private issues publicly. so i responded. my husband is worried about any drama it will cause but not angry. im also nervous but i feel like us repeatedly telling them our reasonings behind our decisions just isnt working at this point. i am at my breaking point
