My boy friend is helpful person or tried to flirting with my best friend?

I was going to Europe to visit my family. My best friend wanted to drop me off at the airport. While we were having breakfast in the morning, my boyfriend called and said he had taken care of the car problem and wanted to drop me off airport. I gave the address of the place where we were and then he came to us. He made an offer to my friend, let's go with a car, we're going to the same place anyway, and my friend accepted. We all went to the airport together. My boyfriend and close friend left me there. Then my boyfriend took my best friend to drop him off in his car. My boyfriend offered my friend "if you need something, just let me know and I'll help you out". Note : There is no situation where the girl needs any help. Then he said "you had a boy friend , then he can help you" made a joke.
Do you think he tried to make this offer a way to get my friend's number or to be close to her?
Or did he ask in a completely human way?
I felt bad when I found out about it.

I think you're extremely insecure. That's a really good way to lose a boyfriend, you either trust your man or you don't. From the sounds of it you don't trust him so you probably shouldn't be together

It was probably innocent
