He texts me first, then doesn't reply?

Stay away from him. If you have yet to establish anything serious with one another don't talk about anything remotely ual. He sounds like a d-bag and obviously isn't putting you first like someone who is genuinely interested would. I've dealt with a similar situation; he didn't act like that but wanted to discuss those things...he was obviously a user.....so stay away. If you haven't had a date yet then he is obviously only interested in one thing. Dump him and move onto the next guy....and although the thought that he may be busy is relevant, if someone really likes you they will make the effort.
