Getting the woman into the lifestyle.

Second question requires some background.
I'm TG, so I'd like to grow my own breasts, live as a woman, and that is fine by itself - but I've got a problem, my woman isn't into ANYTHING along those lines. Which would be an easy solve, but her name's on the mortgage.

I figure any way I can get her gone helps me, as she's not supportive of the TG stuff. But she might become supportive if she got into this sort of lifestyle...?
Or, she might find a man she likes better, and leave. Score 1.

Now, hormones will ******* my sex drive (as if she doesn't already - accept it, she'll never change, don't want to explain, other than - her thigh is bigger than my waist, and I'm not skinny.) And if she gets into this, it could be interesting to see where it leads. But - how do I push her to look outside our relationship? Tacit permission is possible, explicit not so much, and I think her guilt would stop a lot. Besides trying magicsis that might not work anyway, is there an easy way to push her along a little? Has anyone here had to push the wife, and been successful? I mean successful as in, she decided to cuck him, feminize him, even leave HER (afterwards, no longer him).

would love suggestions. I'm average, and I am good at oral, so i've already built quite a tie with her... Need to break it, and passive-aggressively giving her an alternative would be a great start.
(And witholding sex hasn't worked. :-P )
