Yes or no with male friend

So, my girl friend has asked if should could write another single male that she knows as a friend. We, currently live very far apart,, and she says a lot of things like she's very lonely and just wants a social life. I understand her being lonely,, because I am lonely and missing her as well. But the question is,, what are the thoughts around her mailing another single male. This other male is just a work friend that she met at work and they never socialized out of work. She says to me all the time that she is truly in love with me.

Thoughts, is this okay or bad for me?

How is writing someone a social life? Tell her to go out.
