James:
Your parents or guardians thought that he was a very sweet boy. They quickly noticed how charming he was towards you and that you had fallen for him. They still didn't completely trust him with their daughter though.
Sirius:
They didn't like him. When they heard you were dating a Black, they were very shocked. Even though he wasn't like his family they still disliked him. He was the almost the opposite of someone they'd hoped you'd date.
Remus:
They LOVED him. From the second he stepped inside that house he'd won them over with his polite personality and intelligence. They knew their daughter was in good hands.
