I love you but I'm not in love with you
A fancy way of saying 'I don’t love you' but with more words and less honesty. It’s like a bad excuse to keep things simple and keep the drama low.
'I love you but I’m not in love with you', said when you asked them to marry you and they just wanted to keep getting free pizza.
'I love you but I’m not in love with you', said when they found out you were a better partner than their ex.
'I love you but I’m not in love with you', said right before they texted their ex.
