I don't know what to do about this woman

I [29M] am struggling with what to do about this woman [30F] I'm in a talking stage with. We matched online in December while I was out of town, met early January and went on a couple dates. Early on she told me she's a very slow mover and was direct that she takes time before she is comfortable having sex, etc. Fine, not a big deal. We had a lot of deep conversations, went on multiple dates, she was very enthusiastic, sending me pictures of herself and being flirtatious, etc. Overall going well, though she has been fairly guarded in person this whole time. I got a bit anxious about her losing interest so I jumped the gun a bit and escalated on one of our dates with testing the touch barrier, nothing too crazy. Next day she sent me a curt message saying she didn't think romantic feelings would ever develop and wanted to end it. Clearly the light touching was too much; my bad, I should have listened. She suggested we stay friends so I kept casually texting her until only a few days later she abruptly told me to stop texting her and blocked my number.

I was bummed, but unfollowed/removed her as a follower on Instagram and tried to move on. She kept looking at my story anyway, which I thought was interesting because it meant she had to be manually looking since it wouldn't show up in her queue. A few weeks went by and she started replying to my stories (again interesting because she still hasn't refollowed) and we began talking again, she unblocks my number and texts me saying "Lets hang soon."

Seems like it's back on. But I have some reservations. For one, she's very hot/cold day to day. One day she's bubbly and talkative, the next day she doesn't want to talk. She's also much more intellectual/polymath than I am, grew up in Russia and went to an elite school, etc. which I feel like would be a problem over time since I am definitely not as smart. But it's the way she's hot and cold every day that just stresses me out. I wake up each day and don't know whether I'm going to get her nice side or her cold side. Maybe it's a Russian cultural thing, she only moved to America a few years ago. She only lets her guard down in brief moments but is normally kind of steely and cold even though she asks to see me often and can be very sweet... some of the time. We have not been intimate yet.

I just don't know if she'll ever let her guard down with me or if I'm just wasting my time... I really do like her but I don't know how much mental space I should keep investing in this
