Ugh...

Just to vent for a minute. Does it make me the bad person for not wanting to try anymore? We've had so many issues with him lying and cheating for the whole year we have been together. Also, we have the worlds worst communication. Sometimes, I think our age gap has something to do with it but then he just can't be faithful or take responsibility for his own actions. I don't want to just walk away but I think it's about time to. How did some of you ladies break it off with you SO?
