My girlfriend said it was a comment for a friend, which said XXX, I love you. Although I know she didn't mean it, I still feel uncomfortable. What should I do? ...

Actually, it's just a joke or a joke. You don't have to care too much. True love for a person will never change. Often, the more joking or outspoken language is, the less true it is. When she says "I love you" to that person in his space, it is actually a joke and a spoof. If you are sincere, you won't say it in space, but in private.

The more many people hide, the more they don't say anything, but the more "ghosts" they have in their hearts! Don't worry! She's not afraid of you knowing, which means she doesn't take it seriously.

Maybe, seeing you feel bad, maybe she will apologize to you. Make way! Girls, we should treat them as children, and then you will be very happy.
