Girlfriends play games online to find husbands, send text messages, audio and video, and make phone calls. Am I right to retaliate like this? What should I do?

Honey, what I want to ask you is whether your revenge is: texting, voice calling or your girlfriend. Do you want revenge? If it is the former, then you should tell her that you are a lover. If you don't do this, you will break up. If your girlfriend is just looking for a husband in the game, that's normal. You can also play with her ID and become a couple in the game.
