For the sake of my peace I gave up.

Me and my ex bf has been together for like 2 years and 7 months already, I do love him but with lack of effort I gave up and he didnt even bother to reach me. Yesterday at 7:00 AM in Philippines which meant was midnight in UK. While hes asleep, my body was finally giving up. I was so exhausted because, for the past few months, I always had to sleep late just to talk to him. I ruined my sleep schedule and force my self to stay awake through the night. Im just ruining myself for the person who just gave me some bare minimum. Yesterday morning I was standing up in the church during mass when everything went wrong. A cold sweat broke out all over my body, and my vision went completely black. My knees buckled, and I hit the floor. When I woke up, I was lying on the floor already people were crowding around me, looking completely panicked. I was shaking, sweating, and I could barely breathe. My body was literally breaking from the lack of sleep and the pure stress of being the only one trying since 2024. He never cheated on me. There was no other girl too. But he just stopped putting in any effort making the relationship 1 sided. I was always adjusting. Whenever we had the exact same fight about it he'll just cry and beg not to leave, but I was so sick already. My heart is failing because of this. Ive holding for so long, but today made me realize something that I had to stop just for the sake of my health and peace. (Any advice? also I did not just faint yesterday it happened before when I was a kid and 2nd last year, idk why its randomly happening to me.)
