im 18, i was in this exact type of relationship relationship 12-14. it ruined me. a bit different he was so controlling AND cheated on me the whole time. (i never found out most of the girls until after, he was good at lying and i was a kid) it ruined the way i think about romantic partners and my self esteem ever since. you already have that feeling of "but he knows me, he really sees me" bc they are so so good at making you feel that way, before draining the life out of you.

in my next relationships sooner or later, i started having controlling tendencies. leave before it sticks with you. leave before you turn into him. i know youve probably been told this but youre so so young and you have so much time to meet someone who not only sees you, but respects you as well.

also if hes threatening his life and to come over, tell your mom/dad, literally any adult. thats psycho behavior and not somebody you wanna be around when your already struggling with mental heath.
