Just gettin caught up with your sitch. Glad to hear your H continues to "inch" his way back into something more meaningful. You're doing a great job, think of where you were as little as a few months ago, things have turned for the better..
KEEP doing what WORKS to draw someone back towards you..let him initiaite, plan, talk, pursue his way right back into your arms and interject a subtle little dose of "hard to get.. " now and then to wet his appetite..
I would tend to agree with your H when he suggests you take all these events coming up this summer ONE AT A TIME, that helps lower your stress level, and take the PRESSURE off everyone involved, and we know how important RELIEVING PRESSURE is when you are attempting a reconciliation with a wayward spouse...
Seems like your H is making some sincere attempts and righting the ship, don't expect to much to soon. As Nik would tend to agree, you can't run a marathon in an hour, its ONE STEP AT A TIME.
You seem to have it down, have a great summer! I look forward to more good things happening to you as long as you stick to the golden rules of how to act around him at ALL TIMES..
" now and then to wet his appetite..
