Very interesting thread, and the responses give a good view of those posting.
I am one of those that do get attached BUT, and here is the caveat - I KNOW it is only fake and never tell them I love them or try to contact them except for bookings.
I look for affection in a booking as well as sex. Even if faked on their part, as long as it is well done and I don't detect it, that is fine - but I am not foolish enough to think they may really have feelings for me. I suppose that is why I have never had a booking under an hour and they are often 2-3 hours long (with regulars who I know). When I am in the moment, perhaps with my head between her legs trying to get her to come, I am in love - but that ends when I come 
When I find one I like, who supplies me with the affection I am looking for, they tend to become a regular. Sometimes, we do become friends - I have had WGs who I have met for coffee and meals, outside of bookings, but I take it purely as a friend, and not a romantic relationship.
Having had EAS for an apparently now-retired SP, I can identify with these thoughts. The SP I see most often these days is one whom I've seen outside the bedroom, in the way that S TS L describes, purely and simply as friends.
I've been to various gigs with her with a meal in town beforehand and stayed - on my own, in the 'Work room'
- at her home afterwards, if it's unlikely that I'd have got the last train home. Unlike the time when I had EAS 7 or 8 years ago, I'm under no delusion that she and I'll ever become 'an item'; neither of us wants that. I know she's had several boyfriends over the time I've been paying her for sex.
