I think my Dad suports me

Since the falling out with my Mom I have been talking to my Dad via email, text and have seen him at an event we're both involved with.  He hasn't treated me any different!  When I've seen him he's given me a big hug and has held me so tight.  I miss seeing him and my mom and even my little sister... I hope that the space away will make my mom realize that this is who I am and that if she doesn't try to understand me or accept me that she may lose me all together.  I haven't directed talked to my Dad about me coming out but I'm hoping to see him this weekend and be able to talk to him alone.  I want to know his thoughts and not let what my mom says make him feel like he can't share also.
