MIL troubles

She's trying so hard to be helpful around the house, but I feel like she is jumping in front of me to try to do things before I do. This morning I put my sons lunchbox on the table, and opened the fridge to grab something, to put in it, and when I turned around, she was putting food in it! So I said "mom stop. I will pack his lunch." And she said "oh ok. Well he already told me what he wants." So I asked my son what he wanted. She is really competitive. I feel like every minute of the day I'm telling her "mom don't do that. I'll do it." The reason she moved in with us was to make it easier on her, not me. I want to be the one taking care of my house and my children and husband. She is really desperate to help, but I need her to be taking care of HER STUFF! It's a huge huge job she has. 

Every time I leave the house, she cleans while I'm gone, she does my laundry, and uses BLEACH to clean the bathroom! We are a bleach free home, I think it's very dangerous, and she agrees with me, but then she uses it while I'm gone. I give her tons of cleaning supplies, I'm a Norwex consultant, so we have lots of super cool, effective, safe cleaning supplies, but she uses her own that she brought.  

She also used to be a chef, and I loooove to cook, and I actually think I'm better at it than her. I finally had to tell her to let me cook, and stay out of the kitchen. The whole time I was cooking she would say "do this, or add that."

My husband is a total momma's boy, so I can't talk to him about it. He gets really defensive. 

I tell her all day long "don't do that, I'll do it." She asks "what can I help with?" And I say "nothing. Have a seat."

I guess she makes me feel like I'm not doing a good enough job, bc she is always trying to beat me to it. I told her she can do the dishes, and fold the laundry, I had to let her do something. And I hate those jobs. She told me those are her favorite jobs. But I don't want her to do anything else, except get rid of her stuff!

And it's awesome being able to leave the kids home with her so I can run errands, so I do that often. But I don't want her to feel taken advantage of. And I don't want to ware her out. And I want her to have lots of time to deal with her stuff!!!

I just feel like a bitch. I'm so cranky. I'm so short with her. I'm trying to be blunt and tell her when she does something I don't like, but when will she get it and BACK OFF! I'm really tense, bc the 2 of us are home all day together. I wish she had somewhere to go occasionally so I can have my house to myself for a few hours, but she never ever leaves, unless she is with me. So I try to be gone a lot, but it drives me nuts. I just want my house back!!!
