I'm sorry you got that reply too, although I do think it's really positive that he suggested going to the proms another night don't you think? There's an opening there for spending an evening doing exactly what you'd planned, just with a different concert. I think that's really positive and it's something of a baby step. I couldn't have imagined him doing that 3 months ago....
In relation to the cat, I think you could either ignore it (indicating by omission that it bothers you), or you could offer unconditional friendship and ask him about it, maybe joking that Maple will be jealous. At this stage I think the point is to encourage him to be open with you about his life and what's going on. if it was me, I'd increase the strings of communication by encouraging him to discuss the new cat plans and moving plans etc. Be as the OW would be, lavishing him with interest and affection..... I know it's hard, but I guess DBing isn't easy
Finally, I'd take the router- nice that he's offering it to you when he could (I guess) just throw his spare away....
Stay strong, I agree with K. There are a lot of positives in his e-mail. If you remove the cat comment I'd be feeling good about the response. Hurray that he liked your suggestion for an evening out. And his loss on the cat because maybe he'll end up with the hissing cat from hell, like that one Rachel had in friends. Ha!
