I am a female born on 14-07-1990 and my bf was born on 20-02-1992. Are we compatable?

Well, you two need to make some changes for a better relationship. Because you both are self-centered, independent and capable, you never surrender to each other. However, a successful relationship and family life needs both sides to cooprate and make efforts together. Therefore, try to compromise when you both have your own opinions. It doesn't matter who win or is right. The key is that your relationship won't be affected.
