I'm SO PLEASED that B got back to you so quickly- I think it's a good example of something that worked in that you were positive and encouraging with him, and said you'd love to see him and he responded by being warm and similarly open.
Based on that, I'd say call him back, or e-mail, depending on what you feel would be most comfortable. Son't leave it too long- definitely get back to him within 24hrs to continue with the friendly interaction. I think it's important to show him you're pleased to hear from him and would like to continue the interaction, just because you guys don't speak to each other that often....
One thing struck me about a previous post in which you mentioned that people seem keen for you to do something different. I wanted to say that I suggested adding 'Love' at the end because it's the standard way in which I'd sign an e-mail to my H, and pretty much anyone who wasn't a work person. It's a harmless but nice thing to write, and you write it to other people, so why not B, who you actually *do* love?
Another thing that struck me about that post was that maybe you're a bit worried that trying something different will reduce the interaction you have with B? IMHO it's perfectly understandable that trying something different would be scary; after all, the status quo is OK, and we don't want things to get worse. However, what if something different helped things get better? What if B reacted to a bit of phone flirting by flirting himself? Wouldn't that be great? If something doesn't work, you can always *not* do it again. You won't have lost anything, but you could gain. Just my $0.02 for tonight! (Actually, just thinking about that, do you have a plan for how to increase the interactions, or what kinds of baby steps would encourage you to try different things on B? I'd love to see the plan, maybe when you have time after finals!)
I'm really SO HAPPY that B got back to you so quickly and positively.
L. xx (with fingers crossed for the rest of finals, not that you need the help!)
Walk on, walk on, with hope in your heart. And you'll never walk alone.
