Good plan, karen. After all, the pi$$y attitude hurts YOU more than him (since he doesn't seem to notice).
The thing that kicked me off was when Journey said, "drop the rope." I took that to mean NOT bailing, but stop looking for results Out There. And then the ankle thing caused me to keep an eye on myself very closely. I think your journaling idea is good, but you might want to "devote" 90% of it to how you are feeling, etc. and only 10% of it to his responses. The answer and the happiness you seek can't be found outside of you.
You're in a rough spot. I believe your H most closely resembles my bf in his attitudes/behavior than any other guy that gets discussed here. I think only good can come from a new approach.
