Online Dating Advice

I'm 21 and I've been talking to this 37 year old mom online. She has a history of online dating, and I'd prefer an online relationship, but she just got out of a rough relationship a few months ago and I feel like she has no time or energy for me.

She didn't know he was married to someone else, and continued the relationship after finding out. The guy's wife found out about the affair, which is why it ended.

The guy has told her that he's dedicated to his wife, and wants nothing to do with her anymore. This happened MONTHS ago, and she still says he loves him (present tense).

I feel like staying with her is unfair to me because she still loves someone else, and I feel like she's never going to get over him. On the other side, if I leave, she might leak my messages with her or my nudes, or dox me.

What should I do anons?
