A man often sends messages to my girlfriend.

Don't think about what is normal and what is abnormal. Now that she is still with you, it means that your girlfriend still has you psychologically. You should take the initiative to pick her up Next time, if she asks here, tell that man you don't have to bother. I will pick her up every day. Don't worry about me. Sometimes you have to be tough. If you want to be manly, you should attack.
