I have a slight attraction towards a friends husband. Do I tell her?

We are all streamers, and all support one another. I started playing a new game that coincidentally he plays too and wanted to play with me. So over the course of 3 or so days we chat on discord while playing. During this time period I could not help but to notice an attraction that I feel for him.

I feel conflicted because I really adore his wife. (I met her through streaming) and I consider her to be a friend of mine. But I am now feeling guilty bc of my light attraction to her husband. Should I talk to her about this or just block them?

Here’s my final consensus: just join a dating app and find someone else to fantasize over so it’ll make me lose feelings for him. Lol.
