Most ts have feelings for clients, they are human after all. However it doesn't always mean they wish you were friends or want to date. It's often more they enjoy your sessions or you say things that remind them of someone
They might even think you remind them of clients past they miss. Who knows?
Just be careful with it all. Don't get top caught up in it. Keep a realistic view of it all so you don't end up like me.
Alot of those things posted here as examples too are just showing some ts are good people. Likely they do that stuff for many clients which being where I am now, is best. I love nothing more than being just like the rest or majority
As long as they don't want you romantically which is very rare anyway, I think you are ok in small doses
