I number closed an hb8 on fb the other day and said that I'd text her when I was out so thr she could join us in the area. When I'm out, I text her where I'm going; an hour later she texts back "Hey! Were in *club*

xx". Different club, but I'm genuinely having too much fun (closing a different girl) where I was to leave, and I forgot about the text.
I should probably have text her back; realised my mistake when I got home about 3 and dropped her a text saying "sorry we couldn't meet up, hope you had a good night x" She hasn't responded.
Can anyone help me on a decent way to reopen her? I see her as a possible f buddy - with that in mind is it best to wait until I go out again and repeat the play or can I create some new circumstances. Thanks!
