Read and advise without insults, please 🙏

I need advice from mature people, please. I will hide some information for posterity sake. I had a boss who was influential before she and her husband started having financial issues. They took loan from people and were running their company on loan. I worked for her for 2 years and resigned when i wanted to get married. I kept in touch but later she disappeared for a while and changed all her contacts and I too couldn’t reach her for almost 5 to 6 years. I tried, and i later stopped. Later, in the last 3 years, I started seeing her back on social media, and I contacted her . She gave me her new number and explained to me what happened to them and how they landed back to square 1. She said her husband moved back to the village and that she was managing herself with her children. She never told me her marriage ended. It was last year that I found out that they got divorced, and when I asked her, she said her marriage went south after the financial hazard.
She started asking me for help with clothes and jewelry. I do travel and i do buy her many clothes and jewelry.
My husband and I are into business. We have hotels, and we run both, though he is not always in the country. we have boutiques in the hotel, where i sell ladies’ gowns and men wears in it as well. I have told our staff that she is my boss and they should treat her like how they treat me. This my boss will call me that she is coming, i am not always regular at both hotels.
But she goes to the hotel closer to her, and that is the one i am not always present at because it’s the small one . I go there like once or twice a week. So sometimes i don’t meet her. She will come, enter my boutique and change into different clothes, use them to snap in our environment, and remove them without me knowing. She will tell my girls not to utter any words like that at all to me. I was suspicious at first when I saw some of my newly brought in wears on her wall, so I felt she could still afford good wear, at least. Not knowing it’s from my boutique. One of my girls confessed to me. She told me that i have been good to the 2 of them staying at the boutique, and she can’t cover such a bad thing. This my boss is now asking me and my husband to loan her almost 2 million. My husband is telling me that the decision should come from me. That she was my boss before. I haven’t even told my husband what I found out about her. She keeps calling and calling me about the money. I don’t know how to tell her that I can’t trust her again. It was last week that I had time and went through her Facebook wall. All the clothes and shoes from last year to this year june were all my clothes. I felt so bad about what she did. And also is it good for her to come to our hotel and after eating all she want, she will ask them to do fresh fish pepper soup for to take home and also take wine home? What should I do?
