Your girlfriend reminds me of when I read a while back where a pregnant girlfriend and her friend decided to “test” the boyfriend by claiming she miscarried to see how upset he would be so they would know if he really wanted the baby.
Needless to say, he dumped her over it.
You don’t test your partner.
If she had concerns, then she should have spoken to you.
Testing others like she did is a childish action, and she’s supposed to be an adult. The term “women mature faster than men” is not always true. Really_Now1 / Reddit
