Most Helpful Guy
I have a buddy who sends texts like that, with cute terme of endearment and everything. They will occasionally contain pics of the girl he's just fucked, sometimes with his dick still inside.

It isn't wrong for feeling suspicious, most cousins wouldn't call their guy cousin 'babe'. Honestly, at that point, I probably would have wanted to see the rest of the conversation, to see if he is telling the truth or not. I don't require my boyfriend's passwords or anything, but if I ever saw a text from someone I didn't recognize, I would get curious, and if I saw 'babe', then him and me are going to sit down for a talk and I would want to read the rest of that conversation, because if he lets someone else call him a term of endearment ('babe') then that relationship is probably getting too close for comfort. What cousins would call another cousin 'babe'?
