Can a 13 year old really be in love?

Although I've avoided using the word in the past I'm starting to think Im actually in love. I think I'm mature enough to understand what love is or isn't. Well he flirts with every1 but me. I don't get him -I sit with him in most lessons & we get along SO well. I'm not arrogant but I think I have a good personality and I'mnot the prettiest out there but Im a fun person 2 be around & a good friend. When we talk I get a little bitof hope that maybe there's a chance for us-but I kno there isnt, he's told me. Next lesson he's flirting with allof my best friends.When I see him smile I always feellike smilin myself but when he's smilin with my friends my heart sinks, it feels like I've been punched!I dont show my feelings 2 anyone except my closest friend, so I try to act like I don't care in case I seem pathetic. But I lookat him &want to cry or run away; I feel so worthless to him, like pure crap.I try not to let him get to me, but have u ever hurt urself and thenthe scar starts to heal but u just keep on pulling it off? I feel like that every day. I spend a while in my room feelin sorry for myself and after I feel a bit better after lettingthings out.Come tomorrow and I'll feel like cryin again. I hate bein apart from him, but bein with him doesn't do me muchgood either. The pain can b overwhelming; I've faked sickness before justto get away frm him &the pain. He's all I think about-I just need to sit with him, look at him and everythin will collapse- it hits me that all his beauty will never be mine. I care for him so much it's unbelievable. Sometimes�I think"if he doesn't want me no one will". It's childish but tbh the only reason I do that is cos he's all I want &need.When it gets down to it i may not mind if it never works between us.When I imagine him happy I dont imagine him bein withme, just the thought of his happiness alone makes me smile. Of course it hurts but I just want him happy. That's how much I care. I want him to see that & to know how much he's loved
