Back-up partner

Imagine you have a toy you love very much. It's your favorite toy and you play with it all the time. But sometimes, you might accidentally lose it or it might break. When that happens, you might feel sad because you don't have your favorite toy anymore.

Just like your favorite toy, a back-up partner is someone you have in case something goes wrong with your main partner.

Let's say you have a special person in your life that you like to spend time with and do special things with. That person is your main partner. But if something happens and you can't spend time with them anymore or you break up, it can make you feel really sad and alone.

That's where a back-up partner comes in. A back-up partner is someone else who you also like spending time with and who likes spending time with you. They're kind of like a spare toy that you can play with if something happens to your favorite one.

Having a back-up partner doesn't mean that you don't really love your main partner or that you're not committed to them. It's just a way to make sure that you have someone else to turn to if things don't work out with your main partner.
