Okay, how should I handle today since I totally backslid yesterday?
Do what you did day before yesterday- GAL! Quit worrying about your H and how he's going to react to every little thing. It seems clear from the convo you posted that HE was the instigator. Like you said, you can't win. So don't get drawn into it! Let him throw his little tantrums, you just focus on yourself and your GAL activities.
