MIL who treats MY husband like her husband. It's CREEPY.

Going to rant here. I am beyond sick of my Mother in law's crap. She's controlling, manipulative & my husband doesn't see it. He puts her before our family & I'm getting real sick of both of their crap.

Her dryer dies. She had MY husband buy & install her a new one. With OUR $$$. Not hers! She's financially comfortable & can afford it. She didn't even ask.... It was EXPECTED for us to bail her out.

She calls at least 3 times a day & texts him NON-STOP. She honestly feels like a mistress. Has to know where he is, what we're doing, what we're spending our $$$ on. Things that are NONE of her business & highly inappropriate to ask about. ( We are both middle aged adults. With a teenager and a preteen. ) I mention how inappropriate she is. He gets defensive & doesn't see it.

Last week her refrigerator died. She had my husband cancel his plans 3 days in a row to come over to her house & try to fix it. THEN....has the audacity to TELL my husband he is going to buy her another one. NO!!!! Our finances are not hers. IM his wife. Not you.... You stupid cunt. We just spent $500 on a dryer for her... With NO thank you. It's just expected from her son.

She constantly asks him to pick her up & drive her on errands. ( She's independent, has a brand new vehicle & no health issues) So he'll drop plans with me... His WIFE. To drive her around town. The spend ALL day with her. Ridiculous. If it was once in awhile it would be one thing. But, it's ALL the damn time. If I go with them.... She wants to sit in the front seat & have me ride in the back of my own vehicle. I just find it extremely rude.

I find their relationship creepy. Am I being unreasonable? Is this normal?
