I like Jody's advice about being a bombshell who's there, full of fun and life, and then gone. You ARE the primary woman
When Jody suggested I bond with H over a complaint I used my tube journey the first time (crowding, delays etc- I appreciate it might not be the ideal complaint with H), but what about poor restaurant service, or maybe the expenses row? I've been bonding with random people outside the polling station over that this morning. Fish ponds indeed. (As an aside when I tried to bond with H this way he looked at me in a perplexed way and did what my H always does....nothing(!))
I think I have a good line in friends who flirt. It should be a fun and friendly 'no danger' type of flirting. For example, yesterday I was chatting with the office IT guy (John) and it went something like this....
IT guy: I have to change your password. What shall I change it to? Me: (smiling) What about John? IT guy: That's too short Me: OK, what about 'John Is Hot' IT guy: (laughs like mad) You need a number in it, so that won't work. Me: OK, replace the o with a zero. IT Guy: I can't do that. Choose something else. Me: I can't think of anything else now. All I can think is John Is Hot. (And laugh and walk away)
But around that conversation everything was pretty IT related in content- it was just a harmless jokey flirt. Maybe you could interject something similar next time you see H? Not the same, but the general idea? I hope I'm making sense.
Don't assume that H's lak of response implies a rejection, BTW. You never know what might be going on in his world- maybe life is getting hard with OW and he's trying to work his way through it. That's what I hope/wish anyway
