Sure, it is possible to be with one person for your whole life. My parents were, and so are many other couples that I know. The odds are with those people who know themselves very well and are emotionally well-edjusted, who have a commitment to their partners and a willingness to give and take, and who are mature enough to understand what life may hold. Often, such couples also share a common faith or belief system.
Good luck; if your boyfriend is the right one for you, I wish you a lifetime of happiness!
