im 13 so i maay be able to helpp.
well i dont know this guy to well but he SEEMS to be playing head games.
its possible the girl in the blog could be you, but if your good friends and he thinks relationships"arent healthy"
he may be risky about having one with you.I think you need to talk to him and let him know you like him.whetherits in a subtle way (as in giving hints)or just coming right out and letting him know. boy troubles suck but its better to talk to him and faill thn neverr try and live without knowing. im sure you wont be disappointed. good luccck [:
