Wouldn’t know how to fully answer that because I’m far from 40 but I’ll try the best I can. I would think she’d be interested in me if she wanted to spend time. I’m no expert in relationships or women but most of the time when a women wanted to spend time with me it most likely ended with her clothes off. Every girl isn’t the same but from my experience women don’t waste their time with you unless they want something. She might want a friend, a lover, a sugar daddy, someone to talk to, etc. I’ve never hung out with a women who didn’t want anything. I’m young so not sure if you can relate to my answer but just wanted to give my input.
