Isn't it a bit suspicious? Or am I overthinking it?

My friend's fiance just texted me and then unsent his messages. After I sent "?", he said sorry. It's ok I said. Then he said he accidentally texted me instead of his friend. It's ok I said again. Then after 2 mins, he apologized again. I didn't answer to him. Then he went through my profile and liked an old post of mine. Then, after some mins, he texted me again and said "please don't tell anyone that I accidentally texted you. I don't want my fianceé to find out cause she is going to ask why did I text you & what did I text you". I said "ok I won't tell". And he replied with "thanks. You're so nice!". Ok good night I said, and thus ended the convo.

Well, I didn't like this tbh. I thought about this, and said what's wrong with my friend finding out about it? After all, it was an accidental message. But then I thought he probably didn't want her to feel bad cause she is sick now, and in the hospital. But then again, there's nothing she could worry about. Am I overthinking this situation?
