Hormones and MIL don’t mix!

Am I just hormonal?? I’ve been staying with my MIL for about two weeks since I’m pregnant and my husband is on deployment so he insisted I shouldn’t be alone. (I’m just visiting not living) Usually I get along great with her, but I’ve always had my husband around and only for a week or less. Well I’ve been going CRAZY! She told me today that she feels like my baby is her baby... the one I’m carrying in my stomach is hers... she has over stepped lots of boundaries including financial ones, and just personal stuff. She’s insisted that our child will be “bad” because she will let him do what ever he wants. And that I will be scared of her because our son will threaten me with grandma if I don’t give him what he wants. I get she probably said this in a joking manner, but she already gives the vibe that she won’t respect my decisions as a parent. She even insisted the next time we visit after the baby that we can’t tell anyone we’re here because she wants all the time with the baby.... anywaysss...She’s borrowed money from me to pay bills and I’ve only been here two weeks but I see her buy beer every few days... but I had to pay her electric because it got shut off. And then she asked for money for gas. I gave her enough to fill up half a tank.. and she only had one day to drive to work before she got paid again... so it SHOULD of lasted. But the next day she was complaining to her other son that she didn’t have any gas and that she had to get up at midnight to put gas in our else she couldn’t get to work... but I JUST gave her money. And so he insisted on giving her money for gas and she said no but took his money for groceries...when I just bought some! I know in the past my husband has had to pay multiple bills for her and so has her 3 other sons. It just frustrates me that this is such a regular occurrence! She wanted me to live with her while my husband was gone and told us it was because she could start saving money finally since we’d be giving her money to live there... She is already VERY sure that she will be staying with us for 3 weeks after the baby is born. But my husband might not even be here... so again I feel like financially it will fall on me to help her while she’s staying with us. Am I crazy for even being upset. I think it’s pregnancy hormones because I get petty about every little thing.
