How long was your longest realationship?

Feel free to tell your breakup story because I am.

Mine was 9 months.

He started lieing to me & I was getting really curious why he hasnt told me it when we met... But then whenever I asked him if he wanted to hangout, he'd always say no.. I found out he was cheating & my heart was broken. I had my brothers by my side cheering me up.c: I became friends with his ex & she is now like my bestfriend & when they dated he cheated on her once too..:c
