My therapist frequently reminds me that "communication is NOT what the speaker says, it's what the hearer hears." It's easy, especially under stress, to forget that and make assumptions. I, for example, tend to assume that what I "heard" was what the speaker was actually trying to convey. Some other people tend to assume that what they intended to convey was actually registered, just because it's "what they intended". Ideally, BOTH parties to a conversation have the presence of mind to stop and check to make sure the speaking/hearing is being done accurately. But, it definitely doesn't work that way all the time.
I doubt that "your" vet is at a place where he can easily check in with you and make sure he "heard you right". If someone's going to do that, it probably has to be you, at least right now.
Having said THAT, have you ever considered an amicable divorce? This whole situation just sounds unhealthy for ALL concerned and I have yet to see anything to suggest that there's a good way out.
There is a "game" I've been subjected to a lot in my life and it's a "game" I particularly hate. The way this works is the person playing the game asks me something like "What do you think about this?" My first reaction is to give an honest answer to the question, because I'm a little slow at figuring out there's a game going on. When I express an opinion, the way the game goes, I am then told that I was "wrong". "What do you REALLY think?" This can go on a long time, depending on the situation. What it amounts to is the person asking the question has an answer in mind and it's "my job" to figure out what it is and provide it. And to do so willingly and cheerfully.
I hate lying and am not good at it. You know one situation where I WILL lie???? When confronted with that game and given no other way out. These days, my personal reaction to that whole "game" scenario isn't something they'd want to print on this site. I'm not saying that that's what you're doing, but, to me, it SOUNDS like that's what you're doing, at least part of the time. I suggested divorce because I've never found a way to get someone to quit doing this sort of thing and I no longer think it's worth the trouble. I think your best bet is to try to find a guy who's exactly what you want (if you can) and marry him, rather than trying to make this guy over into something more "acceptable".
