Long term relationship?

context: been in a relationship for 5 years, no house, no ring. we live together. Im not happy and I did step out of the relationship (yes I feel horrible) not asking for sympathy because I KNOW I chose to cheat. I know this means I don't care about my relationship. He is a good man and wants to work on this but I can't anymore after what I did. can we overcome this? do I stay and work on it?

Long term relationship?
