I can't tell if I'm falling out of love or just overthinking things

Alex
My boyfriend and I have been together since the beginning of this March. He's amazing. I can't imagine my life without him. We haven't been apart for more than a couple days since we've been together. But we had to spend the past week apart and I started wondering if I was actually in love with him or if I just want to be in love with him because he was my first everything. I missed him so much and I was so excited to see him when I got back yesterday. And when I saw him I felt just as happy as I always have to be around him. So I can't tell if I was just overthinking everything or if me thinking about maybe not being in love with him means I'm falling out of love. I have a lot going on in my brain right now.
