I mean your nice and all
When someone says you're okay but they're trying to be nice so you don't get all dramatic and cry in the hallway.
You: 'We should be best friends forever!' Them: 'I mean your nice and all... but I'm not going to your birthday party.'
You: 'You’re the best!' Them: 'I mean your nice and all... but I’m dating your ex.'
You: 'We could have been great!' Them: 'I mean your nice and all... but I’m going to the prom with my crush.'
