He (mostly) seems nice online: should I meet him in person?

I'm 13 and I really need some help. I have been talking to this guy for ages on my phone and texting him. We have Skyped, and I know he might be 'one of those older people who have random children acting for them and they have voice filters' etc, but he has Facebook and I know loads of people who know him, but I just haven't met him. He is really nice and we both wanna meet each other......
