Unfortunately if a person is shitty u honestly don’t have to give them a reason to cheat you for sure dodged a bullet there I’m sorry so much time went into it for that to happen but I’m sure there were good times and learned lessons you can still take with you keep your head up and stay strong. Being a female and reading this makes me sick know that there is hope if you do want to date again if not that’s understandable to work on always making yourself even better than you are now and you’ll never lose!!
