Hey, Native...hang in there...this is a LONG road we're on. I hear you about the difficulty of seducing when she won't date you, but if there are opportunities when you see her, try being a little flirty. Make lots of eye contact, maybe notice something about her appearance and compliment her...maybe a slight touch. I dunno...I'm acting like I'm an expert and my own sitch isn't all that great.
Anyway, it sounds like your wife has some pretty big issues with self esteem and such. Has she thought about counseling for herself? Did you guys every go together?
