So I knew this girl before covid and we were co-workers for the same company. We kinda lost contact during covid then she started reaching out to me saying she had some new app idea and that she wanted to meet me, she said it was not only to work on the app but that she's lonely and doesn't have many friends and that I could go to her place and spend the night if I wanted.

Calls and texts were coming in waves when it rains it pours sorta thing. She was saying how I have to meet her urgently to talk about the app. I met her but then to my surprise there was a much older guy there too. Now they certainly came together and went back together, the app I guess didn't work out and she stopped texting me abruptly, until one day when she texted me for that other guy's contact info. Which is weird cuz I assumed they were together.

Bottom line is what do you guys make of this and any advice for what I can do?
