You seem to have a lot of insight into how you've handled things. When we are low, even a bad love can seem better than no love - as the old song says. In the long run, though, that's not really true. You have the wisdom to see that. Sometimes what we do that hurts in the short term can be for our welfare in the long run. (Like having a painful medical procedure that prevents/treats a worse problem.)

You've been seriously unwell, and this guy doesn't seem to have a clue about helping you through that. He probably wouldn't change. Try to have a plan for the next weekend that will get you out and with people, or just make a set plan to go somewhere, even only window shopping.

Thanks for your expression of concern for your readers of this thread. To even think to say that when you're as low as you are is unusual and shows a maturity on your part. That's a good thing to build on.
