My (m23) wife (f24) has thrown me out without reason.

I'm at a loss for what to do.<br>I've been married to my wife for almost 3 years, and honestly I've never been happier. We have a 2-year-old son.<br>A few weeks ago she told me that she wanted to talk to me, and that she was upset. I didn't do anything and she didn't give me any hints about what was wrong.<br>She told me she wanted to go to a concert so I dropped her off.<br>She didn't come back to the car when it was finished and I was devastated.<br>The house was empty and my son had a low temperature, so I went home and took care of him. She sent me texts saying she slept at her friend's place.<br>A few days after that she said she was going back to her parents house because she wanted to be alone. She didn't let me come and didn't come back to the house.<br>She told me she was at a bad place and didn't know what to do, but she didn't say what exactly was wrong.<br>I'm not sure what I did wrong. I don't know how to make her happy again. I'm really worried because she hasn't called me in more than 10 days and she's throwing our son away. I haven't been to her parents' place to talk to her because she told me to stay home.
