It's hard to say goodbye after coming a long way. 

You cannot deny maintaining a relationship is not easy. It takes a lot of effort for two individuals to build a relationship. However, in between this journey, some of them fail and, it is absolutely fine to end things instead of draining yourself in them. 

No doubt cheating hurts, but many other things in a relationship can hurt just as much. And this Reddit thread talks to us about what kills a relationship other than cheating.

6. "Growing up/growing apart. A few of my friends had what I lovingly call "starter marriages" in their late teens/early 20's - they thought they were so grown up and taking the next step in life by getting married. The reality was they still had a lot of growing up to do and were basically playing house. As they continued to grow and mature, they often realized they were different people with different life goals."

11. "Being punished for what their ex did to them. Such as hearing about all of the wonderful things that she'd do for that undeserving ex.

14. "Manipulation - My ex-fiance used to tell me about how uncomfortable she was around her dad and that she didn't like how he touched her sister. Naturally, I was pretty hostile around him and, he seemed to reciprocate the feeling back. I found out later that she was telling him the same things about me. So that we were fighting over her. Dodged a bullet on that one. Also, self-diagnosing herself as cured of bipolar and MPD. Went off her meds and, all hell broke loose. That became a big deal breaker for me in future relationships."
