Advice in a relationship

Hey I will just try to sum this up as much as i can , so yeah i have been in a relationship since two years , and in the last months everything has changed so basically her friends hated me and started to tell her i am bad and she should leave me , and during this period she treated me so bad and threatened me to end everything after every single simple argument , even though I am really lover boy and everyone tells me that , she also claimed that she just talks a lot about me and in good way , so this day her bsf litteraly snitched about our rs to her mom , we are at Highschool and her mom is a bit strict about those ideas , we didn’t talk for a month because of the problem , then she came back and whenever we argue she said u argue with me after i lost all my friends for you ? And she just blames me a lot and she says i am the reason for her saddens even though i promise i am chill not perfect at all but not as she believes , now we can not obv meet bec of her mom and we barely talk and she is most of the time dry , and yeah she sometimes tell me we are not in relationship , and we are just waiting to marriage , she does this so I don’t ask her who u talking to , if she did …. i am also moving abroad for uni but I would still visit but i dot know really and i am Exhausted but i still genuinely love this girl
