Sharing Our Innermost Thoughts

I Uh, broke up with my girlfriend yesterday. She was being shitty like I loved her and I did give her things and words she loves, we always had a good time and she did those back to me. We were perfect to each other full of love and care but then she started flirting with that one friend of her, and it was inappropriate flirting that should be said to lovers you know not friends, I confronted her and she use that ‘‘I know I acted immature’’ Excuse and that she took my love for granted, I hated that so much and I still do but I miss her now… She kept begging for me to give her a chance and said ‘‘You promised to stay with me for the next two years’’ then I said, ‘‘How can I stay with a person who is flirting with their friend like that?!’’ so we havent talked in a day after the break up, I didn’t give her a chance since she needs to learn instead of thinking i’d always stay. I really wanted to let her stay but I now that I have to let it go, she should learn that her actions affects things in life you know? I love myself so much so I don’t wanna make me be all sad, have breakdowns, overthinking and bad shit but this does hurt.
