MIL issues venting

ok I just need to vent some! me and my mil have never really seen eye to eye. she thinks she has this like foot in the door when it comes to my family's decisions. (me and her son and the kids) she tried to convince her son not to marry me and she is always quick to baby him and get involved where she shouldn't be. so anyways we lost everything we own to a hurricane a few months ago and went into alot of debt trying to get back on our feet. we have had a few bills we haven't been able to pay just trying to get caught up on more important bills and she has been getting calls because she was a reference on some of our loans.so without asking us she went and took out a big loan and gave it to my husband to catch up our bills. which was thought full I just don't think that was her place to do that. all she did was pile on another bill that we can't afford. I feel like if she wanted to do that she should be responsible for paying her loan off.am I wrong to be so upset over it cause now it's just another bill we can't afford to pay! idk why my husband didn't give it right back and say no or go pay it right off. instead he did what she wanted AND THEN told me about it. I am just so upset I can't hardly eat, it's making me sick!
