is missing your boyfriend like this normal?

So I just left my boyfriend after spending 2 days and nights with him. We are in a long distance relationship for the summer we attend the same college but since it's summer vacation we dont see each a lot so I got us a hotel for 2 nights. I was so happy being with him I haven't even been home for 24 hours and I'm crying missing him. I'm so in love with him. I wish I could have stayed long but I just didn't have the money. He lives 3 hours away. Gosh I feel weird crying about this.
