Friend with benefit ghosted me?

I was friends with benefits with a woman for about a year. I have not been lucky financially and had to lean on her financially as a result. 

I told her up front that I was struggling financially and could not afford to take her on dates or buy her anything. I offered some company and intimacy which she seemed okay with as she was going through a hard time emotionally (she had just separated from her cheating husband). We saw each other once or twice a month and would have light conversation most days.

I admit that i asked her for support a few times and she did help with bills, car rides, groceries and day to day costs. She also got me a job and ran errands for me. She was helpful tbf. But after a few months she started to complain and would occasionally bring up things she had done for me. She even once sent me a text detailing how much she had spent versus how much I had. She said that I had spent £4 and she had spent £4000. Rude! Clearly she was keeping score. She also used to cyber stalk me, my friends and ex on Instagram. 

She eventually ghosted me after I asked her to help me to buy a new computer. No conversation, no argument, no nothing. She changed her number and came off social media. So I had no way to contact her. I stopped trying after a week. After a few months she's back on social media and i have a feeling she would want embarrass me on there. I also think she is still looking at my profile. 

What should I do? 

No judgemental answers please!
