I'm not really easy to live with! There needs to be unlimited patience and unconditional love. Men I've known before loved my independent spirit and were proud of my success, to the point that they'd become jealous of the time I devote to my career.

This quote is saying that it is not easy for someone to live with the speaker. Although the speaker’s independent spirit is appreciated by people she has known in the past, too much success or too much time devoted to her career can make them jealous. Because of this, the other person in the relationship must have a lot of patience and love the speaker unconditionally.
