This could be something I wrote..
I am exactly the same with my cg. Today I am abroad so not able to do anything more than text my cg. After last night i sent a normal text. I have had a combination of silent treatment, plain abuse and rejection.
I always fall into the trap of texting back (because, like you I’m a fixer, so don’t like to leave things unresolved.) i often wonder what would happen if i just stopped. If i stopped fixing. And didn’t reply like he expects me to.
I’m on the same rollercoaster. All i can say from my experience is that they cannot meet your emotional needs right now and what you are feeling and the emotions you have building up probably don’t really matter.. So you need to look after yourself emotionally first. Do something for you.
After that, everything seems a bit calmer.
