I am horse woman (11.aug.1990) , and my boyfriend is rabbit man (2.aug.1987)

what are possibilities of our relationship .
Will it be life long or just like a peach blossom.
Sometimes i don't like him being so insecure and clingy . So i end up shouting at him .
He is nice but now its getting very irritating.
And sometimes i like him him and other i don't feel like he understand me .
