Sandy, back off a bit. I know its hard, I am almost in the same state you are and I can relate. He is not choosing to ignore you, he cant tell you anything more. In his head, he is doing his best. He maybe having lingering feelings but those feelings are not the issue now because you should consider on how to strengthen your relationship and not how to kill those.
You gave him some clear messages. He did too. He says he is providing for you (act of love for him) and that he is bored (not always but agrees with you). So, solution based Sandy, what can you do about that?
I would not send another email while angry. I would reread yours and his reply. Yours sounds like you are panicking. That can not be very attractive, can it?
Go back to the basics: GAL, PMA and stop obsessing over him and his thoughts. Even if you feel he cant see it, he feels it. Regroup... K
