Hi Yoke.
I am so sorry you are going through this painful time. it hurts and we get it here.
Shall i just walk away and never turn around? Is that the best for her and what she wants?
No one here is going to tell you to stay or leave. What we will do is help you sort things out and take a closer look at the reality of such a relationship and what you can do to possibly reconcile, if that is what you want.
It is kind that you are asking what is best for her and what she wants. Right now, she is clearly saying she needs space. The best thing you can do is give that to her while working on you and deciding on what your want and what your needs are. She needs time to settle down emotionally. You will have little chance of her hearing you and responding in a positive way if you do not give her space. If you pursue her whether by text, email, etc, she is only going to push you farther away.
Take time to talk with us, focus on you and your needs and slow things way down. Post on the board so we can all help you. We have a lot of collective wisdom here so take advantage of that.
What do you want? What was the most troublesome area in your relationship? Lets talk about those things and then see what we can do.
