Leo and Scorpio battle for control

I'm a Scorpio woman in a relationship with a Leo male for the past 8 eventful months. My relationship with him is pretty unsteady. He is basically a warm and generous person, but not always that way with me.

He always wants me to open up and share all my feelings although he doesn't do the same. And I feel afraid to open up to him because whenever I do, and our thoughts don't match, he calls me a fool for not agreeing with him. I know most Scorpios would kill the guy in this case, but I'm not a typical Scorpio, as in, I'm not very revengeful.

Whenever we have discussions about any topic, his primary aim is to prove that I'm wrong, even if I'm right. And I find it a bit hard to stand up to him. I'm a very sensitive person who finds it hard to open up and he tends to act as a steamroller, completely disregarding my feelings. I go out of my way to please him but he doesn't even say thank you for the favors I do. If he's angry at me, instead of telling me upfront, he just cuts me off and goes partying with his guys. Sometimes I think he does not care at all, but sometimes I thinks he does care, but this is just his nature.

My head is a complete mess. Even if I tell him not to do a certain thing as it hurts me (like comment on how skinny I am), he still does that to either test me, or prove that I cant tell him what to do, I don't know. Someone please tell me what should I do? I'm crazy about him. Insanely crazy. I'm madly deeply ridiculously crazily in love with him.

PS: The between the sheets part is great, I really enjoy that. although he is slightly selfish in bed too. but still, its fun :)
