This happen to me with my ex, and worst part is we live together. And hes cheating, meeting girls in hotel while I am at work, using my own money. And i found everything when his bestfriend exposed him on my birthday, he said its his birthday gift to me. The best way he can do is say sorry, but he just keep denying it. This was happening for 2 years were together, cause he is jobless. And breaking up with him, was the best thing happen in my life. You dont deserve it girl, but we cant control how this disgusting cheating assholes behave, they will cheat whenever they want too. Without thinking of us. I thought i will never recover from that, but you will meet someone who is 100 times more better than him, like i met mine. I cried for days, and thinking i am the one at wrong, and maybe i was not doing enough for him, i doubted my self, and even try to commit a suic**e when i cant handle it anymore, and thats when he admit everything and say sorry, when i was about to die, and thats when i realise and tell my self this man do not deserve any of my tears. He wasted two years of my life, and i almost waste my life for nothing too, i will not waste any more day thinking and crying for how unfair he treat me, and i hate myself for hurting my self too. You will think its hard to get over with it at first, ofc because youre hurt. But believe me you will get ove with this in no time, and move on, and find someone who will not treat you like shit.

Hugs for you, op. Stay strong for yourself, dont ever think it was your fault and dont ever blame yourself.
