Honestly Kent, I can understand you feeling like the ex is treading on your ground. My thinking is LET HER GET around the family if she wants and they agree. Let them start seeing more sides of her. If they want to talk about you, its their thing. Let them. Dont let that bother you.

Just make it clear that what they do with her is not to be brought up with you.

Let them keep their business on thier side if that is their decision to do so. Just as long as its not brought onto YOUR side.

Maybe they need to see a "little more" of her to get a good picture.....and you just keep trottin along like you have been. Their doing, not yours, even if its out of politeness that they are allowing this.

Just keep moving forward and try to let it go.

Maybe Im wrong, but thats my thought on it.
