My mother makes me so angry!

First let me say that I love my mum and she loves me and we have a mostly good relationship.

Now the hard part.

She is so incredibly jealous of anyone I spend time with and so poisonous about it! It was one thing when she was being toxic about my best friends as I was growing up - I endured, but taking the same attitude with my husband is unacceptable!

My hubby thinks that my mom is very fond of him, which isn't true... She is just socially savvy. Every time my husband is away, she demeans him to me. She also demeans my in-laws by extension (only in my hearing)! I have been firm with her and told her I don't want to hear her speak about my husband since she clearly cannot be positive. Now she goes around telling people that I have become distant from her and implies that my husband is to blame! The trouble with her is that she is always playing coy and always expressing everything in a seemingly charming way that makes her look like the victim. I don't know what to do about her!

God, I love her so much, but she makes me want to rip out my hair! She never acknowledges her mistakes and never apologizes, but I am sick of her games. Anyone else in a similar situation? Any advice towards building a healthier relationship with my mom?
