Need to vent about MIL!!!šŸ˜”šŸ˜”

Iā€™m 34 weeks, my baby will be born in sometime December. My boyfriends mom said she wanted to plan everything.. i said okay even though i have major anxiety about thought maybe itā€™ll be less stress if someone else does do it. Anyways, she says the shower will November 24. Right after thanksgiving.. i said No! Thatā€™ll be hard for a lot of people because they work Black Friday and itā€™ll be crazy, not only that but it doesnā€™t give me enough time to get things i didnā€™t receive at the shower. Like a crib or whatever. As i said before i get major anxiety and need to plan things ahead. She says thatā€™s the only time she has off to plan everything and ā€œshe has 30 people that already said theyā€™re goingā€... i said whatever.. even though itā€™s my shower and Iā€™d like my family to be there not so much people she knew and worked with that i didnā€™t even know.. i let it go and make the invitations and send them out with the date. 40$ later. She then says sheā€™s going to BJā€™s to get food and cups and supplies, she comes back with one set of forks, cups, and plates and rice. She gets a plain cake with no decorations on it and she said sheā€™ll do it herself because itā€™ll cost way more. I said okay..? She said you owe me 250$ for everything.. i told my so why are we paying for this stuff when she said she wants to do it? WHATEVER I GIVE HER THE 250!!! Going broke already because we just paid for the hall that was 350!! I look in the fridge and say whereā€™s the meat? Whereā€™s the sauce? Whereā€™s all the stuff she was going to cook? My so said she has it, itā€™s gonna he okay. The foods gonna be all set. I get super mad because what was the fucking 250$ for? She said the cake was 100$ how was a plain cake 100$ when i had a designed cake for 30 people that was only 65? She calls today and says she needs 100$ for food!! I flipped!!! So pretty much i gave her 250$ for crackers for HER house, waters she kept in HER car, rice only thing for the shower, and chips that her younger son kept in his room and a bunch of frozen quick dinners when i looked at the recite. So i pretty much paid for her house dinners.. and a half ass cake i didnā€™t want.. MIND YOU SHE USED HER EBT CARD!!! And asked for 250$ in cash. I couldā€™ve done this all myself, got everything cheap with the cake i wanted & got food. Iā€™m so fucking mad right now and feel like Iā€™m getting played on my fucking money and my SO isnā€™t doing shit.
