First, you should understand that zodiac compatibility isn't the only factor that affects your relationship. If you both can't work together to strengthen your relationship, there is no future for you both.

I can't foresee whether he is your future husband. But I do know that your zodiac signs are very compatible. You two are the guys who take responsibility for their own behaviors. You never feel embarrassed or lose face when you admit you were wrong. Honesty is what combines you two together.
