@GawDesmond,
Well, it may not be as simple as that, if kids and property and finances are tied up in the marriage.
It is possible to rekindle marriages. First thing I'd suggest :
- go and see some counsellors to get ideas.
- sit down with her and really listen to her
- ask her where it all started going wrong
- ask her how she's been feeling the last few years
- ask her what she thinks has caused those feelings, etc
A few concepts :
- you put time into what is important to you. Even the busiest people on earth make time for what is important to them. So, have you been putting time into her, and your relationship with her?...or has where you placed your time told her that she is not so important to you?
- you pay attention to what is important to you. So, have you been paying attention to her? Or have you been paying attention elsewhere and essentially telling her that other things are more important than her?
- tiredness makes putting effort & attention into important things more difficult (ie. a lessening of interest), PLUS, if one partner has to put more work in than the other (resulting in tiredness)...the result is both a lessening of interest towards the other person, and blame placed on the other person.
- if you aren't growing, you are dying. Same goes for relationships. They take constant work. Have you been putting the work in to grow your relationship? Or has it been dying?
Lastly, relationships are a two way street - these questions could apply to her just as well as they can to you.
