Stop thinking that way. Never think you're not good enough. I've felt this way before and I realized I was just over thinking. Just relax and go with the flow. He likes you for you, nothing else matters. Love yourself. You can't love someone else until you love yourself. If you do like him and he likes you, just try it, see what happens, maybe he can show you things about yourself that he loves and that you can learn to love. Don't give up because of what your brain tells you. Sometimes our brains just love to analyze and think irrationally, ignore it. Go with what your heart says. Follow how you are feeling. I really hope it works out.
