Should I break up with him?

Kaylee

Okay so my boyfriend had been acting weird so the other night while he was asleep I hacked into his snapchat, well it turns out it was his old snap chat from two years ago, there was this girl on there who he’s talked to me about and to his friends about around me, he’s always like “she’s about 13 and had slept with like 15 guys and she’s always on drugs” and basically just bad stuff, but when I looked through the messages.. they were talking about how good it is when they hook up and they hung out everyday to do stuff. Anyways, that upset me because over the summer she messages him on intagram and asked him for a ride somewhere but I saw it before he did and I was like this is his girlfriend and no he’s not giving you a ride anywhere. I was confused as why she would asked because he had always made it sound like he just heard of her. Anyways we broke up in October and she was on of the first people he followed and he says he did it because he knew it would piss me off because of how mad I got while we were together and she messaged him. So at this point I still dontknow they had sex and everything, I didn’t know until yesterday night so he was following her for like four months and then blocked her last night, well I was looking through all her pics and he liked all her pics even just from when we were together. He told me he doesn’t care about her or anything and most of it was to piss me off but I think it’s a cove up. Everyone is telling me to leave and it’s so hard.. we’ve been together for two years.

UPDATE: I found him commenting heart eyes underneath one of her pictures from when we were dating, he still says he never got ahold of her but I’m not sure. I packed all my stuff and I’m out. I will not continue to do this to myself. I’m so overly hurt and I don’t understand why I was not good enough for him but I have to move on. Please comment advice on how to move on and quit obsessing. Thank you
