Hello. YOu say she is fed up and you say you have spoken to her, but what is the result? What is she fed up with exactly? The answer to this is the answer to your question. You both may need some time apart to regroup and to think about what is really going on and what you BOTH can do to fix the issues you are having. Keeping an open and honest communication with each other is the key. If you go through the issues one thing at a time and do it in a way where there is not a blame game going on, but rather a discussion as to how you can resolve the problems happening in the relationship. You may be talking with each other, but its HOW you talk to each other which will get you results or if you just go in circles. If you both want to be with each other and there are some issues that are just in the way of making that happen so that you are both happy, you need to identify the things she is fed up with and then go from there one step at a time. It's difficult to offer specifics without having more information, but that is the general thing you need to do. Yes, your relationship can be salvaged, if you both work together to do it.

Its possible, if she has a lot of stress in her life in general that the added pressure of having a relationship right now is too much. She may honestly feel she can't put as much into it as she should. Does she tell you specifics as to what she feels you are doing to make her fed up? Or is she vague?
