I think this guy is just not worth the time to be honest, hes wishy washy. I would just let it go. You deserve someone that will want to be with you and not vanish like he is.. Hes probably playing the field .. Thats just the downside of online dating ,...Its a great place for the Player type guys to have there fun. Not all guys online are that way at all .. I think you just bumped into one.
Im sure the next guy will be a better man
