I saw weird message

Ladies Me and husband have been fighting a lot recently, and last night he pretty much stayed in the living room and this morning I saw a weird message unsent to one of his guy friends that said hjknij Babe I want some 🍑😕😎😔 😎 jksnfjejcie a lot of jibberish after that I quickly assumed he was probably trying to message someone else.... so I called his friend that he left the unsent message to and it was his guy friend (not a female) had to make sure it was his guy friend he got mad at me and said im always accusing him of shit without evidence he said that it could have been our baby (2 year old) that got his phone and did that text our son has done it in the past but its very sketchy to me that it says clearly I want 🍑 (ass) and then jibberrish after that.

Any advice.??

*He told me unless you have actual evidence that im doing shit dont accuse me because im sick of it.!
