One of your main concerns in life is having a partner, and that need may sometimes outweigh all others in your life.
Although you are likely to form very strong long-lasting partnerships, an unscrupulous lover may take advantage of your overwhelming need. If this situation occurs, it will be your fault for permitting it as much as your partner's for playing on your weakness.
This same motivation may cause you to try to control or tie your lover down with unnecessary commitments in order to assure yourself that the relationship will continue.
Rather, give your lover maximum freedom, even if that is worrisome at first. Time will bring you the security you long for, as the relationship grows increasingly stable.
