what should I do to win my husband’s trust back?

I am a married woman and recently had a baby. It’s been 2 years of my marriage, and there are so many issues between my husband and me. The main reason behind these issues is my mother-in-law. She always complains and speaks ill of me to my husband. Now, in his subconscious mind, he has lost his love for me and doesn’t even trust me with basic things. Due to this, I am falling into depression. Should I stay in this marriage or move out? If staying, what should I do to win my husband’s trust back?
