what would you do?

okay, long story short.

me and my step mom got into it bad a few months ago. it was over something very stupid, but she basically put her nose in where it didn’t belong and disrespected me big time. she’s disrespected me in the past that i have let go of, and i never defend myself. but this time i did and she did not like that. her and my dad and all my siblings live in an hour or two away from where i live, my grandparents adopted me so it’s just me that lives with them. to sum up how the argument started was i had stayed up at my dads house while she stayed here where i live because my cousin was having her bridal shower and i was not planning on going and she was. however, my dad decided early in the morning that we should go, i didnt have anything with me i didn’t shower or brush my teeth but i had no choice because my dad asked me to go with him and i wasn’t going to say no. however i said i didn’t have any deodorant or even a BRA, okay i was not prepared to go to this bridal shower at all. i called my mom (grandma) she had me on speaker. i said i didn’t have these things and to please bring them when we meet at the bridal shower. my step mom thought i was being a “brat” about this and called my dad. he had her on the speaker in the car, and she goes “since she wants to be a brat and fuck up everyone’s plans, bring her to the house before y’all go to the shower so she can get her own shit” me and my dad looked at each other all confused and i go “wait what is she talking about” she goes “NO YOU SHUT THE FUCK UP” and it started from there. i told her to shut the fuck up and don’t talk to me like that, and she said a whole lot that i can’t say on here that’s how bad it got. okay my dad took her side and i haven’t spoke to them in months. my gender reveal was about 2 weeks ago and me and my dad got on good terms. him and my older sister we’re going to come but not step mom. they get to the gender reveal everything was good. mind you my sister is 18 years old but the way they parent her is just is crazy. our step mom is so mean to them but deep down i think my sister is just scared of her so she kisses her ass. me and my sister were in my room doing our makeup having girl talk, well that’s what i thought. she was telling me about her boy problems, and telling me about her issues with her mom (not step mom) she hates her mom for reasons i don’t think are right at all i just think our step mom has played in her head that she’s better than her mom and i honestly think it’s all my step moms fault why my sister is the way she is. anyways i asked her if she knew what happened between me and her and she said no she knew we weren’t speaking but didn’t know what happen so i told her. that’s it, she cut me off and said omg i had no idea all that happened and that was it, she acted

like she didn’t wanna speak about the situation which was fine i didn’t say anything else. she acted fine through the whole gender reveal, everything was good. NOPE. come to find out she went back home, told them everything i said and she said “it upset her” i overheard my dad on the phone with my mom saying how i can just forget having a relationship with them and that i’m all drama. haha. i messaged my sister and asked her what i said that upset her so much and she didnt say anything back just blocked me. my dad has been ignoring me until i found that out and i messaged him and said i really don’t understand what i did so wrong but i’ll leave your family alone i’m sorry. he didn’t respond. i finally got a text yesterday asking if he can keep my son (6 months old) for a few days. WHATTTTTT??? i don’t know what to do. if i say no, they will think i’m punishing my son for our issues and like i’m taking it out on him but if i’m not even welcomed at their house why should i allow them to keep my son??? after all this shit... i was so close with my dad and i feel like ever since she came into his life it’s been hell. she’s so mean to me. when i had my c section my dad asked if me and the baby can stay at their house so they can help since i couldn’t walk or move or anything. i was in the shower crying bc i was in so much pain plus going through ppd, she comes to the door and tells me to stop crying like a baby and to “get over it” because it’s not that bad. with my son in her arms.. anyways. i know that was a long story but what would you do?
