He is popping the question soon

So my boyfriend and I have been friends for a while before we started dating. We always had a thing for each other but it wasn’t the right time. The right time has finally come and we been together for 8 months now. A few months ago he gave me a promise ring, I have tiny fingers, so we had to do a lot to get the right size and than adjusted.

The other day he randomly ask me what was the size of my ring again and I asked why and he goes “oh just talking about rings, with my buddy, he was wondering your ring size”. I don’t know it because as I stated above, it was the struggle to get the right size and adjusted. Later on that night, when I was doing the dishes I took my ring off. Suddenly it disappeared I’m flipping out looking for it, he didn’t really seem bothered. Like 2 days later, he goes “I found your ring in the bathroom” mind you I don’t take it off to shower, just to clean. He gives it back and the ring is also cleaned. So I know he took it, lately he been on sketchy phone calls with his friends. Today, we took a pictures on his phone and I was deleting the bad ones. I accidentally deleted a wrong picture, so I go to his recently deleted and he has a bunch of pictures of rings. I quickly close out of it, he ask me for his phone, and a few minutes later the pictures are gone. Today, he was telling me a story on how someone asked him about is and he goes “I told them you were my soon to be fi..” and he catches himself and quickly Changes the convo.

What do I do ? Do I act stupid? I don’t know how to feel, we haven’t been together for a year. Is it bad to get engaged before a year mark ?!? Help ladies! I love him so much
