I believe the thing you need to focus on is prayer, frequenting the sacraments, and talking to a priest.
I don’t think discernment means you stop liking someone. It’s putting something good on hold while you discern a potentially greater good: religious life or priesthood.
A vocation is a grace from God. To open yourself to that grace, you would lead a prayerful life, enriched by the sacrament of reconciliation and the Eucharist.
Christ said something to the effect that those who gave up good things, family, wealth, and status for his sake would stand to gain a hundred-fold in heaven. As a religious or priest, you conform yourself more closely to the image of Christ and you die in that state.
Imagine being more perfectly happy. St. Therese’s sister showed her a thimble and a glass. She filled them with water and asked, “which is more full?” They were both full, but the glass was obviously greater. In a similar fashion, you will have greater happiness as a religious - if that’s your calling.
Worse it can come to, you visit a monastery or enter a seminary, and you find yourself happy. If you find yourself miserable, you can leave, start up a family, and be happy. Boldly entering into discernment is a sure way to be happy. You have a vocation, you’re happy. You’re miserable pursuing a vocations, you quit, and you find happiness as secular.
