If you are feeling insecure about a relationship, you need to discuss the causes. Your partner will be amenable to helping you find some balance and may even discover something about themselves in the process. A romantic eccentric may deliver a contradictory note to you. You will not know how to take this. The person is probably fond of you but may also be exaggerating things a tad.
An important key to self-confidence is preparation. - Arthur Ashe
