Hi, I used to be highly involved in the kink community and have met/interacted with/dated people on all ends of the spectrum in terms of how seriously they take their fetish. Now I don't have much personal experience with the whole bimbo thing because I don't appeal much to those guys (short and nerd girl cute) but I've met those men and also dated people who take their fetish as seriously and have compatable fetishes (the whole bdsm sex slave thing).

This is a rabbit hole. With the way he went about this he will be absolutely relentless into talking you into this. A push up bra is not going to do it and will only encourage him to push and push and push until he breaks you.

The reality is that he is not the man you thought you fell in love with, this is a major part of who he is. I'm not even criticizing the fetish itself, if that's what he jerks off to that's fine, but to make it a lifestyle and try to pressure a woman who is trapped with him into it is indicative of something deeply reprehensible.

What is extremely telling is that he did not seek out a woman who also has this fetish. He deliberately sought you out because he enjoys the "nonconsensual" element to it - it's not your fetish, he likes the idea of pressuring you into it. He waited until you had a legally binding document to him to tell you. I know you think your love is different and special and blah blah blah but you don't know him.

He is not mentally ill. Seriously, go try to find this in the DSM. He just finds a) certain things a turn on and b) has beliefs about what women are that feed into his kink. Your beliefs about human nature or the other gender or whatever are not mental illness. Some people believe in God. Some people believe humanity is inherently good. Some people believe women are good for nothing but sex.

You can't get him help, he doesn't want it.
