Mom keeps bringing up my husband's past

Whenever my mom is mad at me or my husband she throws his past in his face or my face basically to say how could I marry someone like him and how could I make a man like this my kids father. My husband is a recovering addict. We have been together for 15 years. He's been sober for 17. He made some mistakes. Went to jail and did some things he isn't proud of to get drugs. My mom aunt actually found my husband's mugshot from when he was 19 and shared it around to the family and it was for drug possession and prostitution. I was angry because that was a very vulnerable moment in his life. He had been crying when they took that mug shot. I didn't appreciate it. I have decided that I want to actually enjoy my Holiday this year and that we will have Holidays with my husband's old foster parents. They invite all their foster kids for Holidays. My mom is upset and feels betrayed but why would I keep going somewhere where I'm shamed. She doesn't have to like my husband's past or him but she needs to respect him. He's my kids father and the man I love.
