Saw a message

I happened to see my wife open a message from an ex on FB. They were messaging back and forth about something she posted. The message I saw said "take care of yourself catfish". I thought nothing of it until we were talking about getting a new fish and I mentioned a sucker mouth catfish. then it dawned on me. He probably calls her that because she was always a great dick sucker and really enjoyed it (until some medical issues made it unenjoyable). I almost got hard right there. I know this guy is the same one that used to tie her hands behind her back, put her on her knees, and face fuck her.
