Sorry for long story.

2 weeks ago I play wechat and I successfully added a vietmoi. She look like local chinese then after I added her only I know she is vietmoi. We have unlimited topic to talk with. When we get closer, she started to video call me.
She look so pretty although I know she work at TFC place. Actually I didn't mind she work at TFC as we are friend. As times goes by I started to fall in love with her. She know that I like her, she will take her picture to me before she work and show me how she wear, reach the place she work she will inform me, finish work also will video call me. I never feel like I have this kind of happiness before. Yesterday she told me she sick because did not reply me much.
She said she going work and I offer to fetch her and she say no because her customer will fetch her home. After that she no longer reply me till now. I know fall in love with a TFC girl is kind of stupid but I middle age and did not have any relationship almost 4 years. I am dry. Guys, what should I do?
Disclaimer: reasonable tembak ok? I very hurt already.
