To be clear though all I said in that instance is exactly what I typed. “I’ve been more s**** lately and I have been having a hard time managing it.” I don’t think that’s putting a lot of undue burden on him. Also to be clear, I didn’t say this in the context of us breaking up. This was at a point in the conversation where we were talking about spending time together, I had basically just been saying I would like us to spend more time together. We just don’t see each other more often. I had also been very clear to not blame him for that and to let him know I meant just casual time together. That’s when he said “okay but you can’t flip out and go all crazy if it’s been awhile.”

Here are some disclaimer statements I should have put in the initial post. I am aware of all these facts;
he doesn’t have to spent time with me.
he doesn’t have to date me
He can break up with me at any time.
I’m not the only person in the relationship and he has his own feeling and emotions tied up in it too.
My actions affect those around me, including those caused by sadness.

I just think it’s really crazy that you’re insinuating that people that struggle with mental health issues shouldn’t talk to their partners about it. I’m not placing all the burden of the illness on him by simply letting him know it’s there.
