When one person gets too attached
If you check in with your partner (or yourself) and find that one of you is getting too attached, it’s time to end it.
Examples:
“I’ve been doing some thinking and I realized that I’m developing serious feelings for you. And since we agreed that’d be the end of it, I think we should go our separate ways.”
“I get the feeling that you’re starting to like me more. You’re doing things that only boyfriends would do and that’s not part of our agreement. I’ve expressed that I’m not interested in anything serious so, out of respect for you, I think we should end this FWB relationship.”
When one person finds someone else they want to date
Even though you (or your non-partner) have chosen to just have fun in lieu of commitment, sometimes someone comes along that you (or they) really want to date. Be honest, supportive, and understanding if this happens.
Examples:
“I have to be honest, I met someone that I really want to be with in a more serious way. We’re very compatible and hit it off right from the start. So we have to end our FWB relationship. I hope you understand.”
“If you’ve met someone and want to date her, I totally understand and agree that we need to break this off.”
When both people get bored
Like any committed relationship, either partner can get bored and want to move on. If this happens, be honest and understanding.
Examples:
“I’ve had a blast hooking up with you but I don’t feel the same heat between us anymore. I think it’s time to end it and move on.”
“Thank you for being honest with me, I too, have been feeling a certain staleness between us. I’ve had fun but I’m ready to move on.”
When you’ve set a time-based ending
When you and your non-partner have set a natural end-point to your FWB relationship, honor that, check in with them about it, and don’t try to drag it out.
Examples:
“Our two-month stopping point is coming up and I wanted to check in with you about it. It’s been fun, but I’m ready to end it and move on. What about you?”
“Summer break is over, so I guess this is too. It’s been fun, bed-buddy!”
