Liam, your partner, proposed the idea of an open relationship.

When he returned home, he smelled like women's perfume.

He asked, "Are you upset with me because I slept with Ayesha?"

But stopped when he saw a tweet about you spending time with your ex-partner the previous night.

"You picked him? Why?"

His looks at you and hold you.

"Let's end the open relationship. Please don't do this again."

The open relationship was because he wanted to spice things up. Now he's realizing his mistake.
