Hey Noelle,
I think morningcalm has a point, but at the same time I was dating at 13 as well. I think the two things I would say to that is stay safe and take it slow, and I'd say leave this guy. Focus on your friends and stuff instead of this guy. Guys at that age (and well, any age) have usually 2 things in mind: looking good with a girl, and getting in her pants. And trust me, you don't want to be doing that now. (I have a friend who had her son in grade 9, so I've seen different sides of that)
Next, I agree with the others, that you shouldn't be with someone if they're ignoring you and stuff. That goes with friends too. Try not to date someone who doesn't also treat you the way your good friends do. Dating for the sake of having a boyfriend happens a lot lately, but I think what's important is having someone who can support you. And despite popular belief, it's okay to be single.
Good luck, and feel free to PM me if you want someone to talk to.
