Is it ok for your husband to allow your mother in law to be aware of marriage problems?

[MARY A]

I dont know if i did good or bad. Past month a went for a vac with my child to see my parents in california. My babies daddy decides to lend my car to his mom which i didnt mind. She came to visit to help us with my step children left behind while i was away. I came back after two week n when i get my car back the hood is messed up. my car is not the greatest car or the worst but it seems it finally gave up on her because the hood lock was not catching. i love my car and the day that i had to a funeral my fiance could not fix my car so he ties a string so my hood can stay down n i wont crash on the way to the funeral. long story short my mom calls im driving with the hood messed up late to the funeral and scared. tell my mother i cant talk, my car is messed up i lended to marks mom and well cant talk this is how i got it back bye. mom calls me the next day wondering if im ok because she doesnt want nothing to happend to me because of you know who(my mother in law)(this is a message she leaves in my voicemail.)fiance hears it and blows up in my face. we start arguing.next day not talking along comes his mom and start asking why we are having problems and why i did this in the past and why i did that. and to be respectful i told her i dont want to talk about it this is between ur son n me. my fiance started telling it over he had it and that his mom had to be part of our discussion no matter what. i keep calm eat with them thought everything was ok. then she came back and started asking us what was gonna happen because it was her bussiness because she was afraid i was gonna leave her grandchildren alone or do something to get her son in trouble. Even though i left my job to take care of my children and my daughter we have together. I never done anything for her to talk or something like that.and they started telling me i need to leave.When i blew up is when she told him well i see that this relationship is going nowhere so im not leaving until she leaves the house. I got up and stated shaking yelling at them i had enough, i felt like i was drowing. I told her this was not her business and for them to leave me alone. i fill betrayed by my fiance and got treated like a floor-mat.
