Your instinct is bang on Elsie. As an outsider reading that email, I can also see manipulation and pouting. This b.s. about wanting emotional comfort can be translated to "I want to come cry on your shoulder whenever I feel weak". It's also a very convenient way of keeping you around.
As for "it sounds like you've already broken up with me"...it's just manipulation. He's trying to guilt you into saying "No no honey! I'm NOT breaking up with you", when it's clear that you're not ready to make any decisions.
Stand firm Elsie. Don't let him force your hand.
