Guy who has a new girlfriend keeps flirting with me? How to confront him?
We're both seniors in high school / 18 years old. He is just starting to date another girl (pretty sure he still thinks it's unofficial) but he has talked / texted with me everyday for weeks now. I do like him a bit but I would never pursue it unless he was single. I don't respond to his texts unless it's a direct question but he still contacts me multiple times daily. I have no idea how to confront him and say that if he has a girlfriend, he should stop trying to talk with me on the side. Should I clear up whether he likes me before telling him to stop? Any advice on how I can fix the situation in a mature way?
TLDR I want a guy who has a girlfriend to stop flirting with me.
