Forgive me, I don’t know much about you, but a couple of things in your post sent up a red flag for me. My comments may not apply to your situation, but I just felt I needed to say something in response.
My ex ended our marriage (a civil one only) because he had always felt drawn to the single life. In his words, “I just never wanted to be married.” He’s not Catholic, so there was no question of “what does the Church have to say about this?”
But the Church does have something to say about divorce. Divorce is allowed for grave reasons, such as the safety of the spouse or children. This does
not mean the parties are free to remarry, of course. But divorce is not allowed simply because one feels he or she has made a mistake, chosen the wrong person or vocation. In marriages in which there are children, the pain divorce causes them is not justifiable except for very grave reasons.
I’m glad that you are so happy now, although I don’t remember where in the gospels it says that our soul purpose in life is to seek our own happiness and contentment.

If you don’t have minor children (and I sincerely hope you don’t), why don’t you apply for the annulment and pursue religious life?
Incidentally, regardless of what vocation I may find myself in, my life is and will remain all God’s as well. This is the vocation of each of us, to belong wholly to God, regardless of our life’s circumstances.
