Is this anger or jealousy?

My husbands brothers girlfriend is pregnant with their second baby. Her baby just turned 1. I’m thinking she got pregnant when she was 11 dpo.

Anyways, my husbands mom has a thing for boys. (Not like that) she thinks that one day they will owe her the world. She already tells her sons, “I suffered for you and now I’m a lone”

My husband pays her bills, furnished her home and is her taxi driver and she still complains. She still has the nerve to talk bad of me to him.

I have two boys and a girl and she treats my boys like prince because in her mind, she thinks they are going to worship her when they grow up. She is not going to mind wash them like she did my husband.

I feel like my husbands brothers gf will never see how his mom is. She doesn’t treat his gf the way he treats me. She’s trying to brainwash her to, and I feel like it might be working.

There was a time when she didn’t talk to me. Because they knew I was mad at my husbands mom and not letting my kids around her. Then the gf had a baby and she started talking to me again.

I already know my husbands mom has favorites and I don’t want my kids thinking they are any less.

Last Christmas she gave my daughter $20 and the other grand daughter $100. I don’t want this to continue but my husband is too far up his moms butt that he doesn’t see it.

I tell him about what goes on and he tells me I’m full of so much hate. I started to believe him…. But I’m seeing again for my own two eyes.

Why do I feel so bitter and full of hate and jealously? How can I stop being this way?

I hope his brothers gf sees how she is… I really do! I hope so soon!
