How do you prevent serious relationship?

Answer

Date a serious person. Also, someone who isn't repulsed by the idea of marriage.

Answer

If you're ready for a serious (steady or permanent) relationship, you must be sure that your partner has the same intention. Don't assume; a successful relationship is based on communication. If two people don't share a common goal, the relationship will only go so far. A strong relasionship is also dependent on the person. A common goal is only half the story; for a long term relationship to last, the magic of the physical part is not more important than knowing and respecting your partner. It also helps to share common values and interests.
