I want an explanation from my ex on why she wants to be left alone.
Do you have some sort of problem with each other?
No, not really. I just want an explanation
If she wants privacy you should give that to her. People need alone time every now and then.
Why? We were together for over a year and she's never acted like this before.
If you love your wife then give her the space she needs. Treat her with respect and care for her when she is down. Honor her wishes and she will honor yours.
