Do you really just ignore guys who want to be more than friends or is there another way?

He is into you, don't let him think you are interested. Some people don't take a hint. Try telling him directly one more time to drop it be honest and open no hiding at all meekness never seems to work in these situations. If he still wont start acting more reasonable then yes lose his number and don't text him back at all. You most of all need to respect your own boundaries or no one else will ever take them seriously.
