Titanic: Did Cal love Rose? Who did Rose marry later?

He was obsessed with her in a stalker/domestic violence type of way but he didn't love her the way Jack did. She loved Jack until the day she died because he was her first true love. She married a man in Iowa by name of Calvert, thus her own last name of Calvert. Based on the life lessons that Jack taught her, she wouldn't have married Calvert if she didn't love him but Jack lived in her heart the whole time. Cal shot himself during the stock crash 1929 according to the news that Rose heard. Watching the movie does answer alot of these questions.
