Should I continue talking to this guy?

[Christina]

I met him through Facebook, but he's friends of my friends that I've known for YEARS. he's 20...which isn't a problem at all considering my age.here's the thing, he's really nice and all...but of say he's going about this MUCH too fast. within the three Weeks or so we've been talking everyday for hours, he confesses his LOVE for me. Id think he's emotionally unstable. He database lot of things, that makes me quite uncomfortable. he has a really messed up sleeping schedule, he goes to bed 7, 8am wakes up three or four hours later, and does it all over again. I for one, am NOT clingy, and he's total opposite. Four o click this morning he texted me a ”mirror picture of himself right after he got out the shower...with done words on a mirror...and he entitled. ”I may or may not be naked”
right after, he listed 26 things he LOVES about me. this made me the most uncomfortable. I told him how that made me feel and he's beating himself over it, saying he hates making me feel that way, and he'll never do it again, and he's so sorry. We have met in person a few times, and he's nothing like that though...he's quiet calm cool and collected...but of he's actually revealing the way he feels about me over messages, should I give him one more chance?
