Women who never found a partner, how did you make peace with life?

I (41F) have been a late bloomer and started dating only in my 30's. I have had two long term relationships, a lot of learning and growing up happened. My last relationship felt like he (39M) was the one until he ended the relationship out of the blue! I have been grieving the breakup for the last couple of months. I knew I was going to marry him! How foolish of me!

I am too late in this game, I don't see how I will start again and rebuild my life. My ex was introduced by a friend when my ex before him ended our relationship. He just came into my life at the right time, he just felt correct. Now I am so lost, heartbroken and honestly just tired of life. I just don't have in me to restart the whole thing, have my hopes raise up and end.

I think I just don't have the destiny of love, marriage, a partner who will fight for me and won't give up on me. I have been yearning for that kind of person, but now I genuinely have lost the energy and just exhausted at the thought of this.

I don't know what life will look like for me, it's confusing, it has no hope. I just want to hear other women who didn't find luck in love or marriage. Please tell me I will be okay alone?
