I am a rabbit, my boyfriend is a tiger. how can i make him to not feel easily board to me?

Well, tiger and rabbit are incompatible because they are not in the same tune. If they really want to make their relationship work, they both need to make great efforts. Rabbit is terrified because of tiger's impulse and bravery. At the beginning, tiger enjoys himself in their relationship. As time goes by, he becomes annoyed because rabbit is blue and insecure.

In my view, both of you should try to get rid of your shortcomings so that you have chances to make your relationship work.
