Emoji to a chicks selfie

Husband and I have been together awhile now. Shortly after we married found out he had been messaging women he met online. We did counseling which helped and since having our son who is now 1 he hasn’t given me any doubt. Honestly it’s been a tough road.

That’s the backstory, so had his phone with me doing something which pictures and just something told me to snoop around so I did. On Instagram he dm a girl just “😎” to her selfie picture she had on her story. I didn’t say anything about it and looking at the time it was when he had been drinking. The next day I look again and he had deleted it.

Honestly how would you feel? How do you even bring it up? It’s frustrating 😔
