I'm a 13 year old in the 8th grade. I recently asked out a girl whom I thought I "loved." But I have recurring thoughts about a girl whom I had the biggest crush on last year. Is that a way of God trying to tell me something about my current girlfriend? Every time I see my old crush my heart skips a beat and my stomach tingles. But I know that she doesn't like me and probably never will. I'm not attractive enough for her in my opinion. I just need advice soon please.
If you read through your Bible, you won't find God communicating with people through feelings. When He had a message for someone He told the person what He wanted that person to know.
Your feelings are your own, but they are an unreliable guide. "He who trusts in his own heart is a fool, but whoever walks wisely will be delivered" (Proverbs 28:26). You can see this in movies that people watch. You can be feeling perfectly happy and then walk into one of those tear-jerker movies. Next things you know you feel like crying and what caused it is a set of images on a screen portraying a made up story! You feelings can be manipulated, but the wisdom in God's Word is rock solid. "Trust in the LORD with all your heart, and lean not on your own understanding; in all your ways acknowledge Him, and He shall direct your paths. Do not be wise in your own eyes; fear the LORD and depart from evil" (Proverbs 3:5-7).
What you are calling love is more of a feeling than true love. Read through Love is Different and see if what you think of as love isn't really infatuation.
