My girlfriend and I are in different places and have a good relationship. I am studying and she is working. Recently, I found that she often goes to the public library to study and have dinner with a familiar male colleague on weekends. I asked her why she didn't go by herself. She said she was lonely, but she didn't have any thoughts about that colleague. I also know that the conditions of that colleague are really poor.

Besides, my girlfriend really doesn't have any female friends who like to study in the library. She works alone in a city and is a little lonely.

So should this situation be accepted? I always find it strange to go alone …
