Closer Together? Will the monkey bring some sort of balance? Any thoughts or opinions?

Hi there, I am born 30/6/1967 (sheep). my partner is 2/3/1986 (tiger). In terms of western and eastern astrology I believe we are completely incompatible. We have a little OX daughter, and the partner wants one more. but the divisions between us have grown strong especially over the last 4 years. Is there any hope? We argue a lot and this will affect our Ox girl. sometimes I feel better to split for the ox sake
