Friends with benefits and female friends?

So my friends with benefits recently met up with his friends girlfriend.

he was calling her and was waiting for her before time, constantly texting too. I did see that he was getting impatient though

Normally with me or other girls, he's late or never shows up on time but for her, he was waiting already. He also went to meet her at the train station rather than wait for her to come to him. Even though he was waiting outside college where they finally came back, he went to the station , gave her a big hug and patted her on the shoulder too.

Does he like her or what? Because its weird how he plays mind games and hard to get with women he dates but woth femae friends, he's totally different.
