Am I being really mean to this guy? Read this please,I need your help.?

[♥Z♥]

So Im 15 and I changed school this year and there was this guy in my previous school who used to like me. Back in grade 6 he openly confessed that he likes me. I told him I was sorry but I dont want a relationship and we continued to be friends. He'd flirt a lot but I ALWAYS made it clear I have no feelings for him. A lot of my classmates thought we were in a relationship byt we never were. Now Ive changed school,and he still keeps texting. Like,he always texts me on Facebook when he sees me online to the point Ive disabled my chat for him. I think he tries to make me jealous,like one day he was like "do you have a girl called ____,in your class." I just said no and it was quite obvious he was upto something. I ignored him completely. He texts me 20x times minimum and I hardly reply once in a week. He texts to greet in the morning,at night and texts A LOT. I know i shouldnt ignore but Im tired. He sends emo texts.
I know I sound like such a b*tch but I am clueless about what I should do? He's a friend I cant say "stop texting " or "text me less often". I thought ignoring him will give him a clue but it was useless. I never initiate a conversation but he isnt stopping. Am I being mean to him? What shall I do? Im a friendly girl and I feel guilty for being mean to him.
But he is being so annoying lately. Please dont suggest telling him straightaway to stop. Im not that kind of person.
Help me, please.

You're not being mean to him. If I were you, I'd continue to ignore him. It might take a very long time to sink in, but he'll get the message eventually... don't feel bad about it. The only options you have are to ignore him, or to tell him to tone it down; what he's doing is borderline creepy.

Just tell him you're super busy and don't have time to text all day. You may need to remind him also that if he has intentions of anything more from your relationship, it's not possible. Then tell him you value him as a friend. It should all be fine

Let him know that you care for him as a friend, and that you like him being your friend.. only. Or just go along with it, or be boring.. like when he texts you, text back boring things like ok, cool, oh, you know, like small little words.. The more you reply with whole sentences the more he thinks maybe he has a chance. It's an easy way to get him off your back without being mean. Or try finding a boyfriend so then he'd have to back off? I'm a friendly girl as well, and I've had situations like this.. Or if he still doesn't stop, you can give in, start dating him.. give it a few days then tell him you can't do this anymore because you feel awkward dating a friend and then maybe that's show him how it'd be to date you so he'd try to find someone else..

Good luck
