Hey everyone, I'm Lea!! Art college student with a passion for photography, books, horror and mystery movies. Recently, a classmate has been showing some interest in me.... We bond over art and shared interests, but here's the complication: he has a girlfriend! He messages me daily checking in and offering support like a partner would, he even invited me to dinner, leaving me torn....... I really like him, but I don't know what should I do :/

Should I politely decline, considering his relationship status, discuss boundaries or something and clarify his intentions or I just keep exploring our friendship, ensuring no romantic expectations?? I'm very open-minded tbh, but prioritize respecting others' feelings... Guidance appreciated!!!
