Why won’t he communicate further?

A man with Asperger’s that I’ve known for years recently got back in touch, joked about marriage and then later admitted to being in love and wanting a romantic relationship with me. Since I asked him out, he seems to have ceased contact. Could he have just wanted to let me know that he loves me back; and wants me, even if he isn’t capable of having a romantic relationship? A few years ago, he said he wanted to be with me, but he can’t bear to be intimately touched because of his Asperger’s sensory issues; and said there’s no point in us dating. We’ve both got Asperger’s, but mine and my communication and sensory issues are only mild. So I’m confused.

Could he have been just expressing his feelings, no more, no less?
