Guys have different ways of showing love, even if it looks like they aren't showing it at all. You have expectations and he's not filling them. I used to be like that, but have learned that though my boyfriend never says I love you unless I say it, it doesn't mean he doesn't love me. It just means that he has never learned to say it.
As for his planning things without you, some guys do that, and I don't know why. I wouldn't take it personally though. I noticed that when I was younger that most of the guys I have been with did that, and as I grew older (I'm 30 now), guys don't seem to do that as much.
Though I can't say if he loves you or not for sure, my guess is he does. He is with you and you are his girl, right?
