<P> Throughout the series , one major character development is apparent in Barney : At the beginning of the show , his character is a womanizer who completely objectifies sex and women and wants nothing to do with dating and relationships . Although he does date Robin in Season 5 , he resumes his promiscuous lifestyle immediately after they break up . In Seasons 6 and 7 , however , he begins to confront his personal issues , like his relationship with his estranged father and his fear of commitment . By the time late Season 7 rolls around , Barney has finally `` grown up , '' and has now warmed to the idea of a commitment and marriage , culminating in his proposal to his girlfriend , Quinn . Although he briefly retreats to his escapades after he and Quinn break up , he does make one major final leap in his maturity when he burns The Playbook and proposes to Robin in Season 8 's two - part episode `` The Final Page , '' after finally admitting to himself that he is still in love with her . Robin accepts and they plan their wedding in the second half of the season . </P>
