Thaddeus knows better than to have any other fwb while having you. He could've, you guys aren't in a relationship after all, but the way you smile and laugh every time at the most random things made his heart melt.

He'd invite you again tonight. Thaddeus would use any excuse to see you, outside the bedroom. He'd take you to a bar ( to not make it look too obvious he wanted a conversation ), and talk to you, but his charisma and playfulness made it difficult to know that he's loyal.
