My H only twice in limbo said he missed me. The first time was unfortunately to my face, so there wasn't much I could avoid. I'm hot headed, which doesn't seem to be your style so I said "That's unfortunate for you, but I miss someone who doesn't effing exist." And then I walked away.
I agree with May with the neutral responses. OK or thumbs up always annoyed the h3ll out of my H when we were in this phase. A lack of reaction literally annoyed him.
I don't know that I really believe in the A and B plan concept. But I do think WAS/WS are spending limbo weighing and measuring the LBS in comparison to either and AP or simply a single life. A non-reaction like OK, does not conform with their idea of what they assumed you're reaction would be. They usually expect the LBS to run to pick the crumbs they're dropping. Occasionally when you have partner like me they expect an explosion or the crumb catching.
Honestly if your H asks about the text I wouldn't lie. It's not worth you're time putting him a hook when he already has you one one. If you're asked directly let him know you saw it, but you have no reason to believe it, and you simply don't have it in you to keep playing this game with him.
He can't have things both ways ad infinitum. There has to be a point at which you won't be willing to play the I love you I hate you game any more. H knows this.
