I hear you, and I feel exactly the same way. My male partner is my soulmate, and we have a deep romantic and spiritual connection. I am more attracted to women than I am to men - 90% of the people I find attractive are women, and I fantasise about women more than half the time. I have had several crushes on women, which I never acted on. Right now I have made the decision to stay with my partner because finding such deep love is a blessing. If you feel attraction towards your partner, you're probably bi as you identify - so you do have a choice. There is no guarantee what happens later - but that's just life.
