Difficulty of the sexes

In class we discussed the topic of Lincoln and his role with women in his younger years. We all know that Abraham Lincoln didn't have the best of luck with women and that he didn't have that naturally ability to talk to and charm them. However, one case really stands out as difficult with women. His romance ended with Mary Owens by him basically convincing her to end it with him. Do you think that he did this because he secretly didn't love her like she loved him or is that he was just so uncomfortable around women that he rather end something that could have been good before he made it bad? Thoughts?
