My ex is getting married and has a girlfriend, but she sent a message saying that she missed you. What should I do?

Personally, I suggest you refuse to reply directly to your ex-girlfriend, because her behavior is childish and may lead you two into the abyss of affection.

The main reason for saying this is that your ex-girlfriend is getting married. When she is ready to get married, if she contacts her ex-boyfriend, this behavior itself is very irresponsible to her husband. In this case, if you have sex with your ex-girlfriend again, this behavior will seriously affect the real life of both of you. You need to look at the past emotional problems as wisely as possible.

You can choose to refuse to reply to any information from your ex-girlfriend.

No matter how good your relationship with your ex-girlfriend, no matter how much you want to get back together with your ex-girlfriend. Because your ex-girlfriend is getting married, you need to be a familiar stranger as much as possible. For your ex-girlfriend, she may want to explain her past feelings by contacting you, but this behavior itself is childish and meaningless.

You don't need to dwell on past feelings.

For the two of you, your feelings have become a thing of the past, which means you'd better not disturb each other's lives. Your ex-girlfriend may still care about your past feelings, but because she is getting married, she needs to be responsible for her present family. For you, you also have your own girlfriend, so you need to be responsible for your current position. No matter from which point of view, there is no need for you two to contact again. You can even choose to delete all the contact information of your ex-girlfriend directly.

Generally speaking, I don't think you need to dwell too much on past emotional problems. This relationship is over, so you two need to treat your past feelings as beautiful memories, and don't ruin your past emotional experience because of your selfish thoughts.
