Friend-I've been there. What Sparkle said is true-we teach others how to treat us and what is acceptable and behavior we will or won't accept. I kept bitching at my husband about despicable and scary behavior telling him he needed to stop, change, see the light, etc, etc. I stayed and each time it got worse, I still stayed, and that taught him it is okay to treat me like that. Well-it's not. I had to pull myself back up abd respect myself enough to walk (run) away for good. I needed to set a good example for my kids-I had failed in many ways at doing that before.
He's quacking (really? Calling you while shacked up with soneone else?! That's NOT love!), he's acting like a toddler and truthfully just wants to test the waters.....keep moving forward, speak with an attorney and move forward with the divirce. I don't know how that could be misunderstood.
