how to say goodbye to fwb

i have a fwb because he said he was going to move interstate at the end of the year. so i thought it was perfect, there’s a time frame, a reason why we can’t be together, he’s cute. we both don’t want anything serious

but his plans to move hasn’t happened.

- i feel like it’s been too long

- the sex isn’t all that great.

- a lot of things happened in my personal life, i’m not in the right mindset for this

- i’m not interested anymore

how do i tell him this??
