He's a manipulative prick.
"He kept going on about it over and over despite me saying NO and also that I didn’t appreciate him repeatedly pushing the issue when I’ve said I’m not comfortable with it. I then told him that if I gave in I would be extremely anxious for the whole period of time and that it’s unfair for me to feel that way for ‘X’ period of time and that the stress is not good for my body and mind."
He didn't accept a straight 'no', so you tried to explain why you were saying no, thinking if he understood the why, he'd let it go. Instead, he just tried a different tack, namely:
"He said that now I was making him feel guilty and that he felt it was unnecessary and not relevant for me to tell him about how it would make me feel anxious and how it would affect my body/mind as he already knows this!"
This was just an intensification of his badgering behaviour, a basic stepping-it-up-a-level because you were continuing to resist. And it's quite revealing, because it let's slip a few things -
- he knew whatever-it-was would make you anxious
- he still wanted you to do it, i.e. he wanted you to be anxious
- he thinks he should never feel guilty for anything he does
"I repeated something my Counsellor recently said to me which is that nobody can ‘make’ anyone feel a certain way. I said to him that if he is saying he is feeling guilty then surely deep down he must be feeling guilty (for pushing this issue) and that I’m not making him feel like that."
Ooh, I bet he didn't like that
! And it's quite correct, only a sense of guilt, of having done wrong, can make a person feel guilty. But, just because he said it didn't mean he was actually feeling it. Accusing you of making him feel guilty was just another tactic on his part. He felt nothing of the kind.
"I’m no psychology expert but I think he might be projecting and not taking ownership of his feelings (I didn’t say this) - trying to force his guilt onto me because I won’t break the rules."
You're giving him too much credit. His 'feeling guilty' was just an illusion. What he was trying yo force onto you was to do as he told you.
If anything, it sounds like DARVO - Deny, Attack, Reverse Victim and Offender. He denied he was trying to guilt you into saying 'yes', attacked you for trying to make him feel guilty, and made you the offender and himself the victim.
"He told me that I was twisting things back into him and using reverse psychology (?) and told me to stop it! I don’t feel either of us have a good enough understanding of what RP even is to be throwing that phrase around."
Aw, diddums wasn't getting what he wanted (your compliance) as easily as he usually gets it, so he's reaching for more tactics to use against you. And it was not 'reverse psychology', not even close. You told him why you didn't want to do something, that's it.
"We’re basically now at stalemate (although I’m not going back on my ‘NO’) because he seems to think I’m being unfair towards him (sounds like he’s accusing me of being manipulative) and I think he’s the one being unfair towards me! And deep down I’m now worried that he’s trying to manipulate me into saying yes."
I expect someone who was selfish and had a huge sense of entitlement would think someone else was being unfair to them just by dint of saying 'no' to them. Doesn't actually mean that person is being unfair in the slightest. Just means your selfish prick of a partner is a selfish prick. And unfair to you.
One question - why are you with him? Because I would bet good money if you weren't, you'd probably have less need for counselling
