Guess it woud've been, because in my mind there's a good chance she comes over if I send that response to her saying she's missing me. Maybe she's just lonely because nobody else is paying attention, who knows, but if she were to come over - what then? Hop in the sack? That seems counter-productive.
I would say for you it is not a good idea because you are still way attached and it would mess with your mind. I chose to sleep with my ex in the end because I was detached enough and knew it wouldn't change anything. Also at the time I thought no PA but now I am not so sure. Being the fact your W is on Tinder you better put a hoody on if you decide to to it. We have had LBS get STDs from their WWs.
