No, it didn't go well at all. He had a massive go at me about other things.
When he got back he was giving me the silent treatment, as he said he wanted to go to the gym and I had asked him if he could perhaps go another day, as I wanted to spend some time together and we needed to talk.
When he got back from the gym he wasn't speaking to me but denied that he was in a mood. Apparenrly, I was annoyed about him going to the gym and have no business being annoyed, as he doesn't get annoyed when I go somewhere.
The funny thing was, in the next breath (because I also went to my (different) gym because I thought I may as well get some exercise in) he accused me of being petty because I got back after him. Apparently, I deliberately took my time to teach him a lesson.
I did a 30 minute gym session! It's hardly excessive.
Also, I wasn't annoyed, I just asked why he couldn't go another time over the weekend given that we hadn't seen each other in days and we had things we needed to do. I felt his reaction was disproportionate.
He then had a proper go at me basically telling me that he is sick of me berating him about lots of things. I told him that I felt he was controlling. I actually stood up to him for the first time ever, pointing out the inconsistencies in what he was saying - effectively 'do as I do not as I say'.
It's not looking good for me. He was totally out of line last night and at one point I felt a bit scared of him. He doesn't shout, but he can be a bit menacing.
Anyway, I'm sorry for this page of nonsense that I've just posted. I just need to get those thoughts out. I can see it's not about him coming in my mouth. It's a bit of a bigger picture.
I'm at my Mum's house in my old bedroom and am going to take some time away from him to think. She hates him so will be glad to help me.
Thanks for everyone's advice.
