Although he cannot follow his heart and marry Marianne but instead goes off to London to marry an heiress and then regrets his actions. He isnt really much of a womanizer, (like George Wickham) He really only leaves Marrianne because he dosn't have his own money to marry her. (Much more like the good Colonel Fitzwilliam) He is just rather impatient and had he waited longer to get married, would have found that he could have married Marrianne, and remained in a healthy happy marriage. Instead of the depressing unhealthy one he found himself in. In short dear readers he's a fourtune hunter, nothing more.
