Theoretically; As any mass approaching the core of a black hole, then would the tidal force difference effect the quantum level and rip apart matter? Also at the very centre of a black hole would gravity cease to exert its force since in any direction the "pull" would be equal?

Well, if we assume that a singularity actually exists in the center of a Black Hole, then any composite objects should eventually be ripped apart by tidal forces.

Also at the very centre of a black hole would gravity cease to exert its force since in any direction the "pull" would be equal?
Again, this depends on what is actually inside a black hole. We have no idea what we will find inside one. If a singularity exists then no, you would always be drawn towards the singularity. It's difficult to think in terms of "normal" gravity, as at the extreme scale of a black hole the curvature of spacetime is much harder to talk about as a "force" if my understanding is correct. I would expect that as you get close to the singularity that the curvature becomes so extreme that there aren't even any paths leading away from it anymore! But, as I am not familiar with the math of general relativity and how it applies to black hole singularities, I would take that with a grain of salt.

Wouldn't it be logical to assume that if the singularity is infinite that it's gravitation attraction would continue regardless of how far matter is pulled in? That it can't have a stationary center because if it did then it wouldn't be infinite?

Most scientists view singularities as evidence General Relatively ceases to work at extremely small scales, not as physical entities. Quantum Mechancs, on the other hand, works just fine at extremely small scales, but, not so much on large scales. This enigma will persist until we learn how to quantize gravity.

I don't follow you. Infinite in what aspect? And why would that affect whether its stationary or not? Stationary with respect to what?
