Sons and Lovers

Sons and Lovers by DH Lawrence left me confused.

The protagonists, a woman and her son, have an unusually close relationship. I think it (their relationship) starts off normal, but as the son grows up, the mother becomes really fixated on her son, in part to escape from her abusive loser husband, and in part to live vicariously through him to the exclusion of her other children. But over time, the relationship becomes unhealthy.

The mother and son become so close that the son can’t love another woman. In fact, the son hates the two women he beds so much that he wants to end his life - because they take him from his mother. Bizarre.
