It's harder to break than to start, I like to remain friend if that happens.
I've never been able to remain friends...not because the relationships ended bitterly...but because they always have lingering feelings.
And yeah, it's hard to end things. But the way I see it is, eventually it's going to happen and I'm not going to get in the way of them finding someone who is better for them than I am - or in the way of my own happiness and finding someone better for me. Gotta pull your bootstraps up and just do the hard thing sometimes because you're doing no one favors by letting things die a slow death.
