His girlfriend has left him for her ex and now he's given up hope of finding a happy relationship (it's a "place he's never been and will never go").
He'll continue to keep on fighting by dating others, but only "for the sake of the tradition." He has resigned to the fact that he will ever find someone he really loves who will actually love him back. Instead he'll pretend to love any person who can truly love him.
Though this will leave him disappointed and aching for the rest of the live, he'll put up with it and become better at hiding his disappointment and unhappiness.
The first two lines are sarcasm.
