a good way to tell if an ESTP enjoys your company is if they like to talk to you and be with you. so give them a little space and see if they talk to you first/hit you up for plans on the weekends. an ESTP doesn't want the emotional part of a friendship that comes with it so they're not very into the sappy stuff. if an ESTP wants to hang out with you, that's probably the best indication without confronting them yourself :)
Hope this also helps you, Anon. :)
