What Am I Doing Wrong? Girl Talk!! Advice?!

Ladies, what do you do when you feel like your guys pushing you away? What could you say to him? How do you get your guy to really open up and speak his mind? I don't want to blame myself because I know I'm a good woman but sometimes I need more appreciation and motivation. But, what if it's because he's going through tough things.. How do you get him to talk about that? & How do I not feel sad because you know sometimes you can't help it.
