Chris, perhaps I'm not the best person to give an opinion on the subject of relationships, but I'm going to jump in anyway. If you've had four years of a difficult and tumultuous relationship, perhaps it's time to take a break from it.

There are times when being in a relationship can cause more stress and grief than the pain or loneliness of being alone. If you've been continually hurt in your relationship maybe it's OK to take some time to regroup. It won't be easy but it might be better in the long run.

Warm wishes for you in this difficult time!
