My intrusive thoughts ruined getting to know someone(advice)

I had one date with a girl, then I invited her to eat, she told me she would tell me what she had decided. Hours later she told me she wouldn't come (she was working and didn't know what time she would leave).

On the next day I asked to have a phone call with her (to clear my mind), she was waiting a call from her work. 40 minutes later she sent me a meme that in short was saying that I was stupid for not listening to her (I thought she was mocking me for making me wait/"listen" for her decision in the past day). At first I joked about it, but then I asked "what's happening?".

An hour later she said nothing was wrong and asked if I wanted to have the call, I said no, and that everything was ok.

I spent the whole week trying to figure out if she didn't make me wait on the day of the invitation or, if she made me wait for hours.

Then finally my anxiety led me to chat with her about that (just ask if she made me wait), but I didn't express myself well, and she turned it into a discussion (in the begining of the phone call I noticed she was crying).

We talked for a bit in the next days. Until we stopped talking.

A month later I asked her if something was wrong in the first date (it gave me a certain relief that it was ok), and I asked if she would like to continue getting to know each other. She said no, and that I shouldn't talk to her anymore.

I've been thinking about telling her I was having intrusive thoughts (the call we had was to figure things out), and that I had Pure O OCD, that was mainly treated 4 years ago. The first week of we chatting was great, then it turned me into sabotaging it due to my intrusive thoughts.

How can I approach this?
