Not sure what to do

Karina

So I found a note folded up in my husbands wallet that said “ I need to talk to you send me a msg this is my number ***-****” it has his number and it’s his handwriting. I asked him who was he gonna give this note to and he said he can’t remember and he asked me where did I find that note and I told him it was in his wallet and he said he doesn’t even remember when he wrote that and he couldn’t remember who he was going to give it to. The first thing that came to my mind was that he was going to give it to some girl at her job or something cause why would he say “send me a msg ” I don’t think he would send that note to a guy friend. Please let me know what you guys think of this.
