answer:This is between your BF and this person. I appreciate your annoyance but cannot help but wonder if you perhaps do not feel a bit jealous by this other person. Be generous with your heart- if your friend likes this person accept them. Be a bigger person and do not let the calls bother you. In life there are no promises, no guarantees and rarely is there a second chance. Perhaps this person is another best friend waiting in the wings.Give them a chance.
