What do you do when the girl you have loved for twelve years rejects you?

I'm so sorry to hear about your situation, I think ultimately just staying there for the children isn't a good thing to do. Children are smart and will pick up on things and realise there's something wrong.

Have you two been to see a relationship councillor together?

Maybe suggest for her to take a break and go off on a holiday with her friends?

Before she made her decision were you two already making some romantic time for yourselves?

I think if you two have tried everything and she still feels the same then one of you will have to move out because it's not fair on you seeing her all the time and it wont be fair on the children if there's constant arguing going on.

In my experience (though I have never been in your shoes so I can't imagine what it is like for you) space away from the person and good family and friends help heal a broken heart. It will take a long time (over a year I think) for a broken heart to mend.

You just have to except that she is no longer willing to be with you. It hurt and painful but there's nothing you can do about it. Give her her space, Are you marry? Who will keep the kids ? Child support ? Is she seeing someone else ? As we grew older we need to adjust to each others needs, may be you two need to make some adjustment in your relationship . Spend more time doing things together, maybe she will remember the good old days.

oh dear, im really sorry about that :(

im afraid you will just have to try and deal with it as best as you can for the kids sake, maybe try going to relate: www.relate.org.uk

so that you can deal with the fallout from a long termer properly, and if it really gets you down try some personal counsellin (just you) as well
