What do you do?

Okie so I have written this blog, deleted it and started over to only delete it again. I know exactly what I want to say but its just not coming out right.

I wrote a blog last night about commitment and love...and my feelings towards it.

I currently have a few friends who are in situations that are similar to my experiences in the past except they may not be where I was when I was in them. Your with someone who spends all their time with you, but yet they won't give you that commitment...its a relationship without a title. What do you do when you are ready to commit yet the other person won't give it back to you 100%? Everything is good 3/4 weeks per say. You care deeply for this person and see something there but yet they just won't open up...they just won't commit. What do you do? Do you walk away? Do you end something with someone that you care about? Do you stick around to potentially get your heart broken? What will really come out of it?

What can I really tell them in terms of advise? I see how happy they are when things are good, and I see how sad they are when things are bad...
What is the right thing to do in this case?
From personal experience, nothing really ever comes out of it...if that person didn't commit the first year into it why will they commit 10 years into it? If that person knows that you will be there regardless why would they give their freedom up? Yet when you build the courage to walk away, that person won't fully let you go and before you know it your are back in the same situation. How is this fair?

They say "you don't know what you got until its gone"..."if you love someone, let them go and if they come back then its meant to be"...yet why is it so hard to actually walk away? Why is it so hard to let that person go? The fear of knowing that if you let this person go and that they don't come back sits in the back of your mind, so even though you know that you have your answer if they don't come back you don't want to face the truth and let them go. So you stick around in hopes of it just getting better. But does it actually get better? You find your self saying...I'll just wait it out until I'm fed up...when I'm fed up I'll be done with it...but does that day actually come?
Maybe you subconsciously know what the right thing to do is...you don't really have the questions in the back of you mind and you are just prolonging the heartache? So you stick around and put up with the BS and still hurt just to avoid that real hurt!
Its hard to walk away from someone that has become part of your life...and at the same time you stay hopeful that maybe one day things will actually change even though deep down you know that they won't. In the end you have the answers to all the questions...its just something you have to grow the strength to deal with instead of avoiding it just to save your heart from really breaking even though its already been broken. After a broken heart there is only one thing to do...start working on the mending process...it takes time and even though it seems like the impossible...your heart will heal, the pain will eventually stop hurting and without even knowing it your heart is healed. Your heart is stronger than you sometimes believe it to be. All the answers that you think your mind has are actually coming from your heart. Your mind is what keeps you confused. So take the time, clear your mind, and listen to your heart!
