For those people who had their first relationship and firsts in everything to only one person, how did you deal the break up when things didn’t turned out as planned? Mine’s story: 23F and 24M

I 23F and I met my ex M24 last year. He was my firsts in everything; to be specifically, my virginity. I was known to be a man hater and so strict about dating. Well, not until I become stupid and fell in love to someone who is not worth it. I gave everything. My energy. My love. Efforts. Etc. Stupid as stupid as it sounds, I love him more than he could. I know, I know, I am so stupid for living under one roof with him the first months we’ve been together. I was so madly in love and the thought of nurturing the time he have months here before he go back go his home country. I acted like a wife and showered everything to him. I compromised and completely forgot about myself and my wants. I kept adjusting to what he wants for being afraid that he will leave me. I thought loving him more will make him stay.

Now, he broke up with me bec of his girl bestfriend. Long story short, he kept going out with her since we started LDR for 5 months and inside the 5 months, they always go out so as his gf that moment, I put limitations on how frequent they go out. And also the thing where they watch cinema by only just the two of them or if he goes to her condo by just the two of them. Saying that he is not doing anything wrong. But he doesnt want that and he feels like it is against his values and autonomy. Xd

So now, I feel so bad about myself for losing my virginity and I feel like I let myself down and disappointed it. I want to feel sorry for myself but idk where to start. How did y’all cope with it?
