What is the theme

The poem, essentially, talks about love in a male-female relationships and what is expected from that love, focused more on the men's expectations. The type of man this poem talks about is a man who feels endangered in a relationship with a woman who doesn't fit the stereotypical expectations of a meek and submissive partner, a woman deemed "difficult" to love. Now, in order to not lose the one she loves, the woman is ready to compromise, as seen from the lines addressing her trying to change herself, lose who she is. But, what is the cost of that? To lose oneself for the sake of someone who didn't see your worth from the start?
