I asked my girlfriend how many ex-boyfriends she had. She told me that there were none, but I told her about the space that day and found that there were two in the end.

Hello, I'm glad to answer your question.

The reason why your girlfriend said that her ex-boyfriend had been to her house before, and now she says that she doesn't have an ex-boyfriend, may be that she forgot to tell you this before, and she didn't realize that you lied to you this time and immediately understood her lies.

As for why she wants to hide her emotional experience, I personally think the possibility is as follows:

She thinks her past love experience is insignificant or even sad at least for now, so she thinks it doesn't matter whether she tells you or not, so she plans to hide it.

She is afraid that if she tells you that she used to have a boyfriend, you will ask too many things she doesn't want to mention.

She may be embarrassed to tell you about her past emotional experience, for fear that you may think that she has rich emotional experience because she had an ex-boyfriend (girls are thin-skinned and don't like to admit it-)

There are secrets in her past experience that she doesn't want to be touched by you, so she deliberately avoids similar topics.

However, in any case, it is not a big problem for a girl to hide her emotional experience. Personally, I suggest that you don't have to care too much about this. After all, the most important thing is whether she loves you now. If she loves you now, what happened in the past is not so important. When you have a deep relationship, the topic unconsciously touches on her past, and maybe she will say it herself ~

Please accept it if you are satisfied, and you can ask questions if necessary. Thank you for your support ~
