HELP! What should I do.

One of my good friends husband texted me through Instagram today saying there was something about me he felt super attracted to!

My first reaction was, wtf?! He has never been flirty towards me and I would never see him in that way!

I am planning on telling my friend even though it will hurt her marriage and she might resent me for that 😔

My husband and I have been going through a very rough patch, and I want to tell him but I am worried he will get overprotective at me being at my friends house (which I kinda understand). I also think that if i tell him we won’t be able to hang out all together any more.

What do you guys think?

*** UPDATE

I ended up telling both of them (this happened on the same day I got the message)

My husband is not controlling, I should have specified that it was more so being at my friends house with her husband would make him uncomfortable. Either way, I don’t think I want to be around my friends husband anymore. It’s just too awkward

Thanks for the suggestions!
