Should the father leave and be with his wife and child or stay and continued to grow his business?

Okay so I saw this on Facebook and in the comments the people were being super rude to the OP saying she is selfish. I’m wondering what your thoughts are?

Backstory: the husband got handed down his family business and is living in a home rent free. The wife wasn’t happy living there anymore because she was too far away from her family. She said that since she tried to live there with him, he should now try to “start fresh” with her in a new area to be closer to her family. This means giving up the business and rent free home. The husband apparently did not want to so she left with their daughter and moved 1,000 miles away and is upset, saying her husband should have moved with her to be a family and not taking care of his business.

My opinion: I feel as though a wife should stick by her husbands side no matter what, especially when he is working to provide a good life for their family. I also don’t agree with her just leaving with their daughter without making any kind of custody arrangements.
