Decision Time

Been talking to this guy for about four months and we've been on a few dates. He's 22 and I'll be 20 in January but he always talks to me like I'm young and as if I don't know what's going on in the world. He claims that he wants to date me and be with me all the time but I just get annoyed with him even if we are hanging out so I guess my question is should I just end this now or give it a chance... I'm trying to hang in there because I'm all about chances but I don't know at this point...
