You should do whatever it is you think is best for you and your son, Khudoo. It's very typical for a walkaway/wayward wife to be deep into their fantasy, and only focusing on the "fun" parts of actually walking away: doing internet searches on places to live, or learning about alimony payments, or whatever. It's rare that at this stage, she'd be displaying the kind of emotional and intellectual maturity to delve very deeply into the nitty-gritty stuff.
