So my baby shower is tomorrow at noon and we are doing a bbq for it. We have been grocery shopping and cutting grass and other things to prepare for it. Tomorrow we are starting to set up tables and grill the food. Well my older sister messaged me today saying her boyfriend was all drugged up and wrecked her car so asked if we can drive a half hour to get her tomorrow. I told her we cant because we have so much we have to do tomorrow morning. She then starts getting all aggressive towards me saying I dont want her there and I'm making excuses for her not to be there. If I didnt want her there I wouldn't have invited her. Me and my dad were discussing a possibility to go get her until she said that if I didnt want her to come I should have just said so. Am I overreacting for telling her if she wants to act like that then dont even bother trying to find a ride with anyone else because I do want her there but it's not my fault her drugged up boyfriend totaled her car.
