Paranoid Gf followup comment! read!?

Ok please read the question I just asked about being paranoid about a possibly cheating bf. I don't know if I can edit questions after they're sent. I failed to mention the biggest red flag. Back in Dec, I checked my bfs facebook page and there was a sent message to an old school buddy saying he had a kid on the way. I'm not pregnant. He says he didn't send that either that he hadn't been on facebook all day. Yet there was a post saying he chipped his tooth in the bottom middle, which he did but he says he got that when we went to dinner..hmm. please help!
