Letting Go

I'm not very good at letting things go, but I've been wondering lately if it's time for some practice. How long do you hold on to something that's obviously not working. Do you keep holding on hoping that things will get better, that someone will change? Or do you acknowledge what's what and just move on? I've been thinking about this lately. I think part of my personality type is given to walking away from people and things as new ones come along. So I want to be sure it's not that coming into play. But I look at the situation(s) and wonder if it's really any use. Maybe certain things or relationships just aren't meant to be, even if you don't hate each other.
The other thought, is how long do you hope in/for a person. I suppose the answer is "never." I think the Bible says something about "putting no confidence in the flesh." I don't know if it's referring to that or not, but either way, I guess we're not supposed to hope in people but rather in God and just love people. And if you ask how long you're supposed to love a person, I think the answer is "always."

Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up; does not behave rudely, does not seek its own, is not provoked, thinks no evil; does not rejoice in iniquity, but rejoices in the truth; bears all things, believes all things, hopes all things, endures all things. Love never fails.

 But then I have to ask the question what does it look like to love? Can't I love a person from afar? The truth is, I'm tired of it all. I'm tired of hoping, waiting, wishing, wanting, wondering and then being disappointed when things don't work. Maybe it's just time to go.
