My girlfriend works in a restaurant and always drinks with guests. Today, she drank again. We send messages every day and call at night. She said, tonight.

If you can't be suspicious, then break up decisively. Doubts every day will torment you, and you can't do anything well. Even if you don't see it with your own eyes, you can't guess through subtle things, because your own perfect reasoning will make you believe it, but she won't admit it if she doesn't want to break up. You will subconsciously believe your own reasoning, and as a result, after a long period of pain, you will still break up.

No matter what the result is, you can't imagine it. Do things responsibly with the mentality of picking girls. If you can't do this, no matter what she hides from you, you will be separated.
