You have literally no way to know the entire context of the situation. Your examples of how bad a person he is just seem like somebody who is upset as a result of the argument, as op stated, they were having. You have no way of knowing his intentions, you are assuming that he is being a manipulative asshole. There was also nothing indicating that he was trying to pressure her into having sex sooner. At no point did Op indicate that he was trying to force her to do it now. At no point was it indicated that he was doing anything but wanting to see his own doctor, even if he was frustrated with that fact that he felt he had already done it. Most of the things you're using to act like he's an asshole seem to be someone who's upset and frustrated.

Can you honestly say you've never said anything stupid, insensitive, or mean when you've been upset that you didn't mean? Those things seemed to come after OP trying to force him to go to the clinics in their area as opposed to their doctor, which you are willfully ignoring. Her message seems to be "Worry about how I feel and what I want and ignore your feelings so we can finally have sex"

You seem to be focusing entirely on his behaviour and not even remotely considering the broader context that this took place in. One thing I find with this sub is they are entirely willing to just blame men for every situation instead of actually looking at what's been said. From what I've read they both seem to be in the wrong, but as every other comment has shown people are very willing to completely ignore the fact that he is an equal partner in this relationship and is entirely within his right to refuse her request to be tested at a nearby clinic.

She shouldn't have to compromise in her want for him to be tested, even though it's stated he was tested before, it is completely fair to ask again. On the other hand though, neither should he. You're also completely ignoring the fact that OP herself stated that he has been nothing, but kind and respectful and that is the reason I'm inclined to give him the benefit of the doubt. Finally she didn't ask for advice on whether she should dump him or not, she asked whether or not it was a reasonable request, which it is, and whether or not she was being unfair, which she also seemed to have been.
