Is this cheating?

So my friend has a boyfriend and she works at the beach. She is only staying at the beach for awhile and her boyfriend lives an hour away. I guess she felt pretty lonely there but one night a guy at the beach asked her to go to the swimmng pool with him. He picked her up and they went together but it turns out that the swimming pool was actually in his complex where he lived. My friend and him spent a few hours in the pool together chatting and he was giving her piggy back rides around the pool. She then went up to his apartment and he made her dinner and then he brought her home. She did not do anything more but do you think her boyfriend should dump her for it? She was not romantically interested in the guy.
