Not being mean but it really does take 2 committed people to make and keep a relationship...not just one. I can’t advise you, only share from personal experience. The saying, “let go and let God” is appropriate and true. Love should not bring us worry or leave room for doubt.
Ease off...step back, focus your thoughts and energy on deepening your love of God. Read, write, take walks, notice your plants or pets. If your mister is the mister for you, it WILL become crystal clear.
Father God you know us all...give us strength to find and love the partner YOU want us to have. IJN, Amen.

I’ve been in this same position and believe that...pray, ask God to - in His time - reveal everything He wants you to see. Then trust your gut/intuition.
