You must be a marine with that name... My dad was marine so im familiar with that!
I read your stitch and yes it sounds like she is immature you hit it right on the head. If she is blowing off her own kids to be with this guy she is truly lost. Giving her a hicky.. sounds like they are in high school.
I think going dark is the way to go. You need to detach. Gal and get out there and do things for yourself and with your kids.
try to be as calm and collected as possible with them, they are so young and its so wrong that they have to be put through this because of her selfishness.
I wouldn't push, only deal with her if you have to.. concerning your daughters thats it. If she does talk with you, keep it simple and matter of fact.. as if..
How long have you been married?

Happiness can be found, even in the darkest of times, if one only remembers to turn on the light.
