This is a serious condition. It is not gender specific. Most movies and music exacerbate it. It is long-term. And let’s be honest… it can’t actually BE cured, despite the title. So let’s talk about managing it.
Strategy #1: Never watch romantic comedies or romantic dramas. A lot of men do this anyway, and I know some women who don’t let a romance movie come near them. Also, cut all sappy, sentimental, lovey-dovey, heartbreaking, and otherwise emotional music out of your playlist. Discover instrumental jazz or offensive rap… anything but the hopeless romantic stuff. In fact, you might want to just fill your MP3 player with audio books in genres like thriller, war history, and political commentary.
Strategy #2: Develop a healthy dislike for the gender of your affections. Read about psycho, needy women or lazy mama’s boys. Ask your friends about their worst significant others, with all the depressing details. Watch bad reality TV and get disgusted by how awful people are treating each other.
Strategy #3: Do like nuns and monks – devote yourself entirely to a goal or pursuit, discarding all romance and intimacy – temporarily. Take six months, a year, or however long to learn how to do something well. Be single-minded. Be devout. Will the hopelessness away. Maybe you’ll get cured.
Strategy #4: Put yourself out there a ton. Chances are, you’ll either get rejected/dumped a lot, or you’ll find The One. If the former happens, you’ll develop a useful cynicism, beneficial to the goal of eradicating your hopelessly romantic tendencies. If the latter happens, congrats.
Whether or not you’re more traditional about love, good luck to you.
