a single
Being single but not looking for anything more than friends is like having a side piece who doesn’t want to commit.
'I’m single, but I’m not looking.' 'You’re just waiting for the right person.' 'No, I’m waiting for a better meal.'
'She’s single and not looking.' 'She’s just waiting for a better weekend.'
'He’s single and not looking.' 'He’s just waiting for someone to stop talking about their ex.'
