I know that feeling sometimes. It's sad but you always have to consider yourself first, he clearly doesn't. I wouldn't waste time on him if he's going to be like this, let him come to you if he wants a relationship. I watched a friend of mine try and try to impress her father and he couldn't have cared less, it made me sad and I didn't think she could even see what she was doing. Sometimes there's people who don't deserve to have the FULL you.
