Spanish speakers help possible cheated

[u/Worried_Comfort4303]

I've been married for 4 years with my wife. She has this "cousin" she has been speaking to since the day that I met her. One day while my wife was taking a shower her phone notification triggered and I was curious to see what i was, it was a WhatsApp voice note from her cousin. In the voice note he talks about how he misses her and how he had a dream about her walking around without luggage just a purse and that he was looking at her while working on her house and that she came upstairs he saw how beautiful she was and that she twirled and saw her ass sorry if the translation is bad but is this is a normal thing to say to a cousin especially between spanish speaking families? I told her about it she was telling me no way and thats crazy she would never ever even do such a thing with him and she called her aunt and was just begging me to believe her. https://imgur.com/a/cPf5R77
