My friend has recently started dating a new girl and seems to be very much in love with her. Could that be why he's going blind?

I recently found out that they went out of town, but he doesn't have a car. She borrowed it from her ex-boyfriend. Said he was a fool and she was using him.

Then I found out she and her ex-boyfriend went to another city for a few days. And she told my friend that they were with old friends and that's why he was there too.

She uploaded pictures on social media of a room with a big bed, but it's still not clear who she was in the room with.

Sometimes her ex-boyfriend goes out of town and leaves her the keys to his apartment.

It's obvious to me, but my friend doesn't want to see it. Maybe I'm wrong or how do I make this clear to my friend?
