I've dated (and been in serious relationships) with guys that I was friends with first. I decided I'm not going to do that anymore. It's too hard when he gets the friends after the break-up. It's also hard when things return to normal somewhat, but you're never the same as before you started dating.
That said I'm going grocery shopping after work and I'm going to keep my eye out for some mens (although we have no Publix up here, so I don't know if I'll have the same success as the other ladies
)
