What does it mean when I guy told his girlfriend that he thinks she is not strong and independent woman, and he wanted her to be one?

It means run, and he will constantly tell you how you ain't this you ain't that until your self-esteem drops to the floor. This is the first sign, and even if it does seem harmless, he won't stop criticising you.

I dated a guy who would constantly call me weak for being emotional and tell me how I should change, etc. He would also put me down about other stuff if you just did this. You get the gist; he wasn't all bad, and I adored him, but he clearly had his own personal issues he wasn't willing to accept. No matter how many times I tried with him, he'd push me away.
