I think my biggest issue right now is that I still worry about her, because I think she is probably clinically depressed, but denies it. Her behavior is just plain weird. For someone who professes happiness, she spends an awful lot of time cloistered in her room watching TV (my impression from the state of her house, and offhand remarks by the kids.
Jim...if I remember correctly your W has a side room that she spends most of the day in sleeping, watching TV and smoking correct? That alone is pause for concern and IMO is just not healthy and combined with how her house looks (based on your description) I would say your assessment is probably correct. Love is tough and it's amazing what your willing to accept (I get it) but something tells me the more you get out an experience life and other women you will be better off for it.
