Relationships can often be complicated by the smallest and simplest of things. And sometimes those things that seem so small to one may seem NOT so small to the other. It's like, one moment things can be going along great and then before you know it, there are cold shoulders and strained silences. Next thing you know, one or both of you are seeking comfort outside of your relationship. By now, I'm sure you're probably wondering what the hell I'm babbling about and what do "Boundaries" have to do with any of it? See, here's the thing... When in a relationship, I believe that some ex's cannot and should not be considered as friends. Period. And not seeing eye to eye on something like that can lead to bigger problems down the road. It's not that all ex's should be excluded but the ones who can't seem to respect the boundaries of your relationship should be gotten rid of, so to speak.
