Whether she's taking advantage or not the OP is allowing it to happen and in her position who wouldn't take the cash to chat I know I bloody would. People get rich on other people's kindness/stupidity. At end of day if he didn't make the bookings she wouldn't need to chat instead of tuck.
I agree with this totally.From reading the OP's posts it is he who is the maker of the current situation rather than her.When she has tried to initiate her usual service her has stopped her as seeing her as a friend he feels it inappropriate , although the paying seems acceptable to him.Most escorts and agencies do have a line about ' charging for their time and company ' and if this is how the OP is choosing to use his time with her then the girl cannot be blamed for taking the money ; especially if she is a parlour worker who's bosses would not look to kindly on her telling customers it is best not to visit.
If you are treated badly or given poor service you have a right to be annoyed with and have a low opinion of the provider and should not see them again.But as the saying goes , ' Fool me once , shame on you .Fool me twice , shame on me .' The OP keeps returning of his own free will and is responsible for his own actions.
To the OP ; I think you know it is not an ideal situation at the moment otherwise you would not have posted and I repeat the original advice that the only way to find out if she genuinely wants to see you socially as a friend is to ask her and you should do it asap for your own self respect and peace of mind as the longer you leave it the worse it will get.You may prove most of the posters on here wrong and get what you wish for from it , but whatever the outcome it is better than the way things stand at the moment and will allow you to move on.
