Shawushka - I don't think Imago is about fighting, I think it is about finding purpose in our relationships. And that is kind of what I am saying to you, is there a purpose left in your relationship? My recommendation was only to help you answer that question for yourself.
Feelings come and go and are the result of thoughts. You are on here asking this question because you are questioning your feelings and your thoughts - and that is a triumph. Taking a pulse check if you will. It could be that things are broken for you and they can not be repaired. Or it could be that this is a phase that you are passing through. And, regardless, you get to make your own choices about your life and what makes you happy.
