Hi - on the the dating fora (???) - I'm not sure you should assume that H is going to follow through with anything from here.
When I was in my immediate post-bomb stage I registered on a few of those sites out of curiosity more than anything - to see what the grass over the other side looked like - just in case.
Actually, it served the purpose of making me realise I really didn't want anything like that or to share my life with anyone other than my W. And actually, I would probably run a mile if anyone showed an interest in me via that route! Remember, folks usually have to write something in a bio to get registered and they're almost always going to write something which they think will be perceived as attractive.
I know the situation is slightly different here but similar dynamics/reasons might apply.
Anyhow - they're my thoughts FWIW...
Best - GFI
