What are you doing to get yourself into new employment?
Having no on-line freedom, is concerning. Three weeks of a silent treatment has got to be one of the longest, I have heard of, not that other's haven't received longer, but it's the longest I have ever heard of. I used to get a couple days at a time, when married.
The fact, that he's not calling you beautiful, and all those things that bf's do for their gf's, is concerning. What makes him a bf, if he isn't being loving and supportive?
How are your kids, doing, through all of this? Is there any family that you can turn to, a friend, even, temporarily to help you while you get back on your feet again?
