Would you hate your Daughters husband for past mistakes?

My wife and i are both 27 been together since we were both 16 and well she has stuck with me through some extremely rough crap. I battled being addicted to heroin and i was an alcoholic both i got addicted to at around age 14 so yeah and my wife was the reason i got clean her and my 3 sons. Well i have been clean from both for 4 years and i am very accountable to the point that i take drug tests once a week to prove to everyone including my wife that there faith in me was justified and everything. Well my wife told me today that she is pregnant with our 4th and our last since i am going to have a vasectomy done and everything. Sorry for babbling well anyways her parents hate me like they go out of there way to make me feel sh itty about my past mistakes and everything and there just always mean and hateful to me. My wife tells me to just ignore em because they think i am not good enough and everything. Would you hate your wifes husband for this? Even though i have gotten clean and everything.
