Look bonny lad ....
I see one regular in fact I see no one else now, she is everything I want except falling in love mate.
It's business at the end of the day and we do enjoy each others company, yes we exchange texts usually a joke. We do overrun time wise its all part of being regular and I do not read anything into it. You have to adapt to it being what it is a business transaction between two people for sex and companionship. Being friendly can be a part of it of course and ideally itcan make the meeting a whole lot better
