Someone help me figure out my "luck"

I am seriously not allowed to win games or something. I win lane 90% of the time and lately every time. I will be very far ahead. I mainly play top. I know I will win lane and I know I don't feed. I tell my jungler to not even worry about top and to just camp mid and bot. For whatever reason every game my team will just get absolutely crushed. Every game this happens it seems. I just got demoted after playing extremely well. In all 4 of my last games the other team even apologized to me in all chat saying sorry for my team. For whatever reason Riot thinks I just belong in Silver forever I guess. Check out my stats and recent matches and give me some feedback or something please. Anything to help would be appreciated.
