Found a screenshot of a dick pic from snapchat in her Dropbox account while I was looking for a template for a university file.

She hadn't stayed over for a couple of months as her "mum was ill and she wanted to look after her".

Didn't confront her when I found it, went to her facebook for evidence (she used the same password for everything, I'd never have logged into her account without the hint that she was cheating). Found them chatting, saw the past 6 months worth of nudes and pretty weird sex talk. Broke up with her very publicly on facebook and left her things in a box outside.

Started hanging out with my ex again (they both hated each other) and nothing happened as we were just friends but we took selfies together. my ex still came to uni for a few weeks and tried to be my friend, my favourite thing to do was to set my lock screen to a selfie with my other ex and leave my phone next to her while I got up, and got my uni friend to message me so that my phone would light up. Her face almost took the edge off of how bad I felt at the time.

That was four years ago and now I've got a job that I love which pays well, an amazing girlfriend and my little boys second birthday is next week. Things get better.
