If you don't have anyone in mind this is fine, you can just affirm that you are uniting with the most suitable partner for you.
However, love spells require a lot of energy and ability. If you're looking to prove something to yourself, I would suggest starting smaller. My first spell was to get a new pillow for free (the one I had at the time was causing neck pain), and it worked. Actually I got 2 free pillows, very high quality, as a gift from relatives. I never even told anyone I needed a pillow, yet I got exactly what my spell was for.
