I am a rat born on 19th september 1984 and my girl born on 3rd march 1990. what does the future hold

Your girl is a horse. You have different opinions. You have enormous egos. If you two can't agree with each other, then one should give in. Otherwise, the harmonious relationship will be damaged. As long as you can overcome your own shortcomings, you two have chance to have a ever-lasting relationship.

Your wood element can be a problem.Both of you will attract each one because you are Virgo and she is Pieces. Unfortunately, you are wood and she is metal so expect some conflict.
