Something that has helped me is what someone told me here...and that is before you do anything...like call or text your W...think about your motivation behind your decision and if it will ultimately help towards your goal. This has helped me massively! so I hope you find it helpful too.
You need to be careful not to sound desperate towards your W, coz she will see it as you pursuing her which will put pressure on her...and you dont want that. I think if you can remember the above it might help.
You need to think about what the important things are...and what can be let slide. I think if you do comment you should leave off the end bit - the bit about it needing to be fixed and just stick to it looks good...simple and making no big deal of it.
Just as an insight as to where your W may be at...is that if you do chase after her, she'll feel even worse within herself than what she probably already does...coz right now, she would have some pretty conflicting thoughts and emotions running through her mind and heart. Remember that she needs time to heal.
Have you read any other books, at the moment I'm reading 5LL and it is truly insightful...maybe reading more might be something that helps you too.
Stay positive, stay focused and be strong
Dont beat yourself up anymore, but do remember your W needs time and space to heal, just be there for her when you can, I know I would have loved for my H to be there for me through this...
Take care, SG
