space like it wants too? Everything wants to return to an equalibrium so why doesn't the forces in space like gravity, vacuum pressure and all the other forces in nature it seems like everything would end up going to an evened out state

It is. It's just going about it really really slowly. Entropy is the name given to the idea of the entire universe going to perfect equilibrium and it is the driving force behind all that happens in the universe. According to recent thinking, everything was at perfect equilibrium until the Big Bang, which forced everything apart. Nobody knows why the Big Bang happened, we just know that everything that has happened since, including all of human existence, is just part of the universe's steady progression towards equilibrium.

Nothing "wants" to return to equilibrium. Inanimate objects have no wants or needs.
Equilibrium means different things for different phenomena. For gravity, which is the dominant force on large scales, "equilibrium" would mean the collapse of all matter into black holes. This is actually what is predicted to happen on a long enough time scale -- all matter will eventually collapse into black holes, then all black holes will eventually evaporate through Hawking radiation.
The equilibrium that you're probably thinking of is the diffusion of gas in space. This happens because of pressure, especially if the gas has high temperature. However, when there is enough matter, the force of gravity overwhelms the force of pressure.

"Vacuum pressure?"
I'm not even sure what that is. I hope you know that vacuums do not exert pressure.
Anyway, some forces in nature want to spread things out, and others want to clump things together. If gravity was the only force in nature everything would sit in one clump, not spread out. Add nuclear forces and things would resist clumping, etc.
The balance between forces and some as yet poorly understood starting characteristics of the universe cause the variety of objects seen today.

Space has no such nature. As you learn physics, you will learn about the real physical forces and how they interact with matter. That's most of what physics is about.
Perhaps the kind of 'equilibrium' you are thinking of is entropy. You'll need to learn more basic physics before you try to tackle thermodynamics.

Gravity pulls things together, not apart.

there is no gravity in space, that's why nothing pulls toward it.
