my guy bsf is in love with me but im in love with his friend

i feel like shit after snooping through my bf's phone even tho he gave me permission without me asking. i found a groupchat of him, his ex, and her closest friend about having a threesome. all the contents in that groupchat messages are about them talking what positions they want to do, what toys to use, when and whose house theyre gonna do it at. i left his home and felt nauseous on my way back.

i hate my parents sooooooo muchhhh omd. im genuienly amazed at how ignorant and disrespectful people can be wow. like today i went to ask my parents if i could get dreads. i think the ylook good plus theyd help me take less care of my hair and all dat. i made a whole presentation for them, approached them like a damn adult just to be met with a hard no and that these types of styles are disgusting and represnt a gangster image. i was alos told its not a part of my "culture" (im half ethiopian half swiss) then this turned into a conversation about how i was struggling in school the first few months and how i was apperantly "always late". then they started yelling at me becasue they thought i wasnt listening and shit. theyre genuinely so controlling and are constantly lying taht they trust me. i genuienly havent lied to them in like 4 years but yet they still wanna ask my teachers talking bout some at the parents event the ygon ask them. man smd
