Parental Emotional Distance

I saw my dad tonight and I hate how distant we've become. But I also know there are some things about my dad I don't like, so maybe being a little distant is the best way to go. He's so annoying about my med school applications that sometimes I don't answer the phone when he calls. Immediately I feel shitty about it, but still I don't pick up. I know he is only trying to help me, but I like to be independent. Besides, if it's something important that needs to get done, I'll get it done my own way.

Anyway, I know he has a hard time really understanding my sexual confusion and this leads to a growing rift between us. He's uncomfortable with it, which makes me uncomfortable around him and my step-mom. So you've got 3 uncomfortable people that should really be relaxed around each other. I can't help it though, because I can't even explain it myself; so how am I supposed to explain it to him?
