✔ 最佳答案
You need to get proof of her on the dating site, and get picture proof of it, just take a picture or screenshot of it... and then confront her with the picture proof. When she denies it, simply show her the picture proof. (Take pics on your phone it's easy)
If she still denies it in spite of the evidence being in front of her face, then she flat out does not respect you and she's trying to lie to your face. You should honestly break up with her instantly and not look back in that case.
Here's what's probably going on: she probably is dissatisfied with something in the relationship, or she doesn't like you at all anymore, so she is looking to find another man to replace you. She obviously is not going to admit this because she doesn't want to lose guy one (you) before securing a commitment from guy two (mystery man she hopes to meet on dating site).
參考: My advice: If you threaten to dump her immediately unless she deletes the site today, she will likely delete the site because she might fear having no man at all. So do that.
After you do that, you need to start looking for another girl on your own, because this one is only a matter of time before she finds a way to cheat on you and leave you. The only real reason to even manipulate her to stick around, is just to get more sex in the meantime. She doesn't want you anymore however. It happens bro; it's life
