Is it weird to ask a female friend to go watch a movie together? M24 F23

So there’s this girl I like. I’ve known her for about three years, but we’ve only met a handful of times this year, and always in group settings. I usually go to movies by myself, but lately I’ve been wondering if I should ask her to come with me

The problem is, I don’t want her to think it’s a date. But at the same time, I’m worried she would see it as a date, and then things could get awkward the next time we meet in a group

I also have no idea if she likes me back. She calls me bro all the time, which doesn’t exactly help. And a while ago I asked if she wanted to work from a café together, she said she would let me know but whenever I bring it up next time she said she would go alone. That feels like a pretty strong signal that she’s not interested in hanging out one on one

Why is this stuff so hard?
