My girlfriend is now going out with other men behind my back and sending ambiguous messages.

I have finished reading it. I sympathize with what happened to you. Love is the freshest thing. In fact, the best way is not to let her leave home in the first place. The outside world is too complicated and colorful. You said that she stayed there alone for some time, indicating that she felt lonely and lonely during the cold war with you. You think a girl must be looking for someone to lean on or talk to when she is in a different place. At this time, she wavered during this period. Once she enters the world of flowers, she will never come back. In fact, you have been in a passive state. You have no right to break up on your own initiative. She's in charge. She loves you more than she loves you, otherwise she wouldn't say so. Don't do this. Suggestion: Leave her alone and let her grow up on her own. You said she made up her mind. Since she doesn't know her mistake, it's useless to say or do anything. When she is in danger, she will naturally turn back. It's time you took the initiative. Only in this way can we wait and see. She is still immature. I hope you can accommodate her willfulness.
