He is totally watching you and making sure your changes are for real. I remember when I started to notice J noticing my changes. He also questioned them at first. Just keep doing what you're doing, lady
As for the lingerie, I wouldn't go that route yet. I went against the general rule and slept with J while we were apart (every 2 weeks, though it's not like we planned it, lol), but he only said ILYBNILWY for a very short time. He quickly realized that he was in love with me still and tried fighting the feelings. He'd fail while around me. He couldn't ignore the changes.
Anyway, I shared that because I feel that being intimate with him while we were apart, though so heartbreaking for me afterward each time when I would have to face the reality that he still wasn't mine, helped us remain connected. He was open to it. Your H is not open to that kind of contact with you right now, IMO. He does seem to be opening up more. Take that as a positive and focus on you.
