Is it weird to like being alone?

Hey all I just have been dealing with some friends showing interest in me. I have been single my whole life 22 years to be exact and I’m not really used to having male attention like that. The guys that are showing interest are cool dudes but o don’t like them or see them as more than friends. I do not lead them on because I don’t want them to think I actually like them. Should I feel bad for not liking them back? I like keeping to myself and being alone. Am I weird is there something wrong with me? Please comment lol
