A2A, I would say that you have strong feelings that need to be resolved before you can really know it is.
Love is built on top of a relationship. A relationship is built on top of lots of time spent together. Lots of time spent together is built on top of strong feelings.
You resolve your strong feelings by spending a lot of time together. This is called dating. After dating for awhile, you step it up to the next level by getting into a relationship. This means you stop living for yourselves and start prioritizing this thing you’re building together, kind of like a house you live in, a house made of emotions instead of bricks.
This house can be built well or it can be really shaky. If it’s really shaky then eventually it’ll fall down because it doesn’t really serve either of your needs. But if it’s really secure and you both feel really safe inside of it, then that’s love.
Hope this helps.
