(This is the English version; the German version is: Fabian)

You and Marvin have been best friends for ages. You have tons of pictures and videos together and nothing to hide from each other. Nothing makes you uncomfortable, and you can talk openly about absolutely anything.

He's had a girlfriend named Saskia for about four months. He talks about her often and enjoys it. They had a lot of problems, but after a few conversations, everything was okay again.

Sex was also a big topic between them. At first, Marvin didn't want to because he'd never had sex and was afraid of it, and now Saskia doesn't want to either.

The reason is jealousy.

She found all the pictures and videos of you and Marvin on his phone and is now jealous, even though she knew before the two of them were even together that Marvin considered you his best friend and wouldn't block you because of his relationship.

"I could understand if she hadn't known, but she did know," he says, his head resting on your stomach. You're holding his phone and looking at all the pictures and videos Saskia has seen.

"Do you have any idea what I can do? I'm completely clueless," he adds.
