Can you pleae help me with some advice?

I met a guy on FB about a month ago, he's and old friend, of an old friend of mine (do I make sense?) anyways, we've been in touch online since then and I wanna say a little less than a week ago, he asked for my number and for some reason, I felt good about it an gave it to him (first time I've ever done this) We have so much in common. He's really funny, sweet and is very respectful about things, not once has he made a sex joke or asked me anything private and personal, that's why I like chatting with him. The next 2 days he initiated the texting, on that second day, he asked if I could actually talk which came as a surprise to me since now a days people don't wanna talk, only text. I think I'm starting to like this guy but for the last say two days, he's been distant. He hasn't' text me but then when I log on, if he's on also, he'll say hello to me right away. My friends tell me not to be proud and text him first sometimes so as an excuse, I forwarded one of those funny pictures and he replied with a hello but then after a couple texts, told me he had to go and would text me later and never did. Today, I did the same and he said the same. I don't know if he's sending me mixed signals or what. Once he actually insinuated that we should meet (BTW, we live in different states :/) and he'll also leave me flirty comments on my posts. He seems to be interested but then he confuses me and also he hasn't proposed to make voice contact again, I really want to but I don't know how. I don't want to seem clingy. Which brings me to another issue, today he told me that I disappear on him, umm no I don't.. I've text him these past two days. I don't understand, if there are any guys out there reading this, can you please explain to me these actions? I asked my friend about him and she says he's a really cool guy and she confirmed everything he's told me about himself (they went to HS together) which is super awesome because I know he's not a creepy old man. This sounds like an issue a teenager would have and surprisingly, it's not, we are both in our late 20's, so we are both mature people. I usually use online to communicate with friends and family, I never expected this to happen so I'm new at it, can you guys please give me some advice. I love chatting with him and I want to continue to do so. Should I be little more flirty? I would really like to meet him someday but I don't know how to bring that conversation up. I would like it if he liked me, how can I tell if he does? how can I make him interested in me? I feel like I'm 17 all over again :) thanks in advance to those of you who take the time to reply and please, no rude comments, that's not why we're all here.
