Haha I got issues lol

I met this guy online who gave me his phone number and spoke to me yesterday over the phone and than I saw him online on the dating site and I get insecure and start to feel detached because i think why is he online and not texting me. My gosh this is an issue for me, I have not met this guy and I am feeling this way, whats wrong with me, he can do whatever he pleases and so can I, I guess I dunno once a guy gives me his number I am thinking hes only wanting to get to know me. I realize a pattern I start to detach and act distant in small responses when he "does" text me. I got issues, anyone else relate or its just me?
