iirc i think i waited about 5 months after splitting with exh before i got back in the saddle, so to speak
i was quite happy to not have anything serious though, so maybe that made it easier for me 
it was with a friend of a friend as well, i bump into him about twice a year still, usually in the supermarket
and weirdly last weekend he sent me some (in hindsight) rather odd messages and called me out of the blue
i didnt think much about it at the time, but then he called with some rather long winded explanation about his messages and it sounded odd
having discussed it with dp and the mutual friend we have, we all think it was strange, especially because he has been with his gf for about 3 yrs now
i was amazed he still had my number tbh, it must be about 4 yrs since we had our flingette, i havent had his stored in my phone for ages and ages now
i am pleased to say that since splitting with the exh i have not gone without for as long as i was with him
