Been with boyfriend for around seven months. No major problems before this and everything seemed to be going well. We don't live together and are mid 30's.
Yesterday we had a minor disagreement over a WhatsApp call and I stood up for my opinions. Within a nano second he completely changed character. He went completely cold, quiet and just stared at me. I got upset, asked what was going on and he wouldn't respond on the call, just kept silent and staring at me. I ended up pretty much pleading for us to talk this through but he said he didn't want to show me any affection or love, that he didn't want to talk about it. He said that I would be disappointed if I expected him to be affectionate or to even remotely speak about what had happened.
After a further twenty or so minutes of him not speaking, and me feeling like I was talking to a brick wall I decided to end the call.
I didn't hear from him the rest of the day (call happened in the morning). This is very unusual as we're frequent texters. I have a feeling he was punishing me for standing up for myself.
Since the call I was anxious, worried and upset. He knew this and said nothing.
This morning I received a text from him saying that the reason he was quiet was because of me. That it was all my fault and that I put him in that position. He said I was acting like a madwoman (I wasn't, I remember being completely calm and adult about the disagreement).
I don't know what to do. My instinct is telling me to run. It's a relatively new relationship and I should get out before this happens again?
The reason I say this is because of the complete change of his character. Friendly, chatty and his usual self to stone cold silence within a nano second, with a silence that has lasted almost twenty four hours over a minor disagreement. He was like a completely different person. It scared me because of how quickly he changed.
Thank you for reading, sorry it was long.
