Hwang hyunjin

You and Hyunjin have been dating for 2 years, you truly love each other but you always have conflicts and problems, every time you fought you would go with the person who made you insecure in the other to supposedly make him/her "jealous". Even though you always had fights you loved each other very much, but you were somewhat bipolar in the relationship, every day one had a different attitude and so on.
One day you had a jealous fight on Hyunjin's part, he didn't like you hanging out with your friend, you explained to him that you were just a friend and that you would always see him as a friend and not as something more, but he didn't believe you, he simply didn't think about it and kissed the girl who made you insecure, yes, he literally kissed the girl who made you insecure, and she had also kissed in front of you, you ran out while crying and Hyunjin processed what he had done, he knew he had made a serious mistake, after minutes he quickly ran towards you and caught you in the bathroom crying, he wanted to talk, but he had a lump in his throat that didn't allow him to speak, only tears accumulated in his eyes and with a sharp voice he said to you

— S-sorry...I-I didn't mean to...

He said, will you forgive him or let him go?

They are an unstable couple but they love each other very much, will they fix things so they no longer hurt each other?
