Should I just delete her?

Hi guys, just under a year ago, I (30m) created a charity event to move animals from the Ukrainian frontline and also, to integrate Ukrainians with locals.

It was getting difficult, long story, but one of the acts, she (25F) helped me out. We raised a good amount of money in the end. Nearly half a grand.

Anyway, I was in a dark place so I told her that under different circumstances, I would have loved to ask her out. She was fine with my message, 'we did a great thing and she accepted it as a compliment'.

Havent spoken to her since but I like her stories and she likes mine. Of the 6 or so posts i made since, shes liked 5? So yeah. one of my top 3 Instagram friends.

Until a few days ago. she removed half of her 'likes' and her story never seems to appear, I suspect she blocked me. I've no idea why, I just wanted to be a friend.

So, what to do? I think delete her, but keeping distance was difficult, but I did it and now, it seems like wants to cut ties. I dont know why, I cant ask her, but it really sucks.
