when u r unsure of his feeling it would be nice if you both sat down and talked to each other .Honesty is the best way .Tell him what you feel and lok into his eyes when u talk .Its the best way to know if someone is telling the truth.Also go by your instincts .Its very important . If after talking to him you still feel he avoids certain issues then its certain he's not into you .So the best thing to do is to move on .
