Reminds me of my previous relationship. My ex controlled my life and i accepted it because i was very lonely and didnt want him to break up with me and then be alone. And i was so crazy, that i thought, that he did that because he cared about me and loved me a lot. That that was his love language. He was pissed when i visited my parents that i havent seen for months. And would be very angry if i hang out with friends without informing him of it. He would check on my phone whenever he wanted, and if i said no, he would say that i had something to hide from him, which meant i betrayed him. I had to tell him where i was, where i was going, and if we’re not together during the day/ night,i had to send him snaps or gave him attention any other ways. But then at times when i couldnt handle it anymore and had my outbursts wanted to leave, he would cry and beg me to stay and said how much he loves me and so on.
One day during a fight, he told me that he was actually ‘just enduring’ the relationship and it just opened my eyes, that he’s not even there because of love, and then i broke up w him for real.
In the end i was so devastated and asked him for closure as to why he even stayed for so long in the relationship. He said, “yes i did love you but tbh i was thinking of breaking up with you everyday in the last years. But i just didnt do it because i did not have enough self respect to leave, that’s why i stayed”.
