When you’re single, you’re just dealing with your own shit—all your triggers, addictions, unhealthy tugs, thought patterns, and behaviors that keep you stunted and stuck at yesterday. When you’re in a relationship, you’re now dealing with your shit plus someone else’s shit too. Since everyone has shit, this is unavoidable. If you have a story, you have shit. How much of it you’ve worked through depends on how much you’ve worked on you.
