What is the compatability between a libra wood snake and an aries rabbit?

I am libra wood snake woman Oct. 7 1965 married to a virgo wood dragon male Sept 16, 1964. I have been very unhappy in this marriage for a long time we share very little in common and we communicate terribly. In February this year I met a aries rabbit, who has two children and lives with but is not married to their mother. I was not looking for anyone. But we have the same interests and this just work between us. We are in love. I don't want to make a mistake because I know that it is advised for married snakes to avoid marital affairs this year, but I don't want to lose someone I feel like I have waited for literally half my life. Is this just a lovesick madness, a fling? What should I do?
