3. … demonstrate your best self
We're not trying to teach you pretend or lie. However, you should let the person know all of your good qualities. If you know you need to work on something to become a better person, do it and be proud of the changes. Mentally and spiritually people never stop evolving and developing. They work on their personalities trying to improve themselves. The point is not to be perfect, but to strive to be better today than you were yesterday. Also, if you do not feel support from your partner, you're probably dating the wrong girl. Talk to her and ask whether she likes you for you. You're supposed to accept each other at all times.
