When does your responsibility to your "x" end, if ever.

Hello

So at what point does the welfare of my X no longer effect me or my life? Or, because she is the mother of my children does this go on forever.

I guess I am just frustrated because she didn't want to be with me but when things get difficult I am the one she calls.  I give advice about moving on with her life and not living for the kids but she doesn't listen to me.  She never listens to any of my advice and then calls and wonders why things go wrong.

the kids worry about her and I have to go investigate what is wrong to calm them down and reasurre them that everything is fine.

it is just frustrating and all I am doing is venting.
