Your politics are quite confusing, not you personally but your country.
I kinda get most of it, the Senate does confuse me though??

The House of Representatives for each state are determined by population. So, some states have a lot of Representatives, and others have much fewer. On the other hand, each state has two Senators. That helps balance power between big and small states (population wise).
All House Representatives are elected every two years. Senators serve 6 year terms, with one third of them elected every two years, so there is overlap of terms.
Because of those things, the House tends to be more volatile and reactionary, while the Senate is more stable, and deliberative. To put it a different way, historically the House has tended to start fires, and the Senate has tended to put the fires out.
