Am I a selfish person for not caring for my wife needs?

My wife and I have been married for 11 years, have 3 kids, and I thought we were happy and had the perfect marriage. About 2 months ago I had a job offer from the company I work for to work as a manager with higher salary. The only thing is that I have to work from the main office and move with the family (me, wife, 2 girls 10 and 5 years old and a 3 yo boy). I discussed this option with my wife and she was very excited and told me that she wanted to move back home. <br><br>The thing is, from the minute I told her that I got accepted for the new position and we have to move, she has been very distant and angry with everyone. 2 weeks ago I was in the city for 3 days to sign the papers for the house we were buying and she told me that she can’t handle moving because of the girls so we should think about it more. I told her that I couldn’t go back on this because the papers were signed and I was obligated to do so (there was a lot of paperwork and I couldn’t go back on it). She’ve been telling me that she doesn’t want to move without seeing the house herself, and that I should have asked her opinion any time that I made decisions, but I always asked her and she was happy about the idea. In reality I think it has to do with the fact that she will be leaving her family, friends and her job. We had a big fight yesterday because I told her that no matter what she said, I was going to move whether she wants to or not, and she told me she wasn’t going to let me do it and that she is going to fight it. <br><br>I honestly think I have the right here because we discussed it and she was happy about it but now she is acting like I forced her into something she didn’t want to do. So I am starting to think that I’m a selfish person for thinking I have the right in this situation and I want to know of there is something I’m not seeing and how I can resolve this conflict.<br><br>tl;dr wife agreed to move, but now she doesn’t want to and told me she is going to fight it.<br><br>Edit: I didn’t buy the house, I just send the papers to the lawyer and he sent them to the company.<br><br>Edit 2: I asked her this morning if she wanted to go see the house and she said yes, so maybe I should have done that from the beginning. Also, the company is going to pay for the trip and I’m not using her money. I feel frustrated about the situation of the girls being affected by the move. My children are everything to me and the thought of hurting them is making me very sad and frustrated. I just want to do the best for them.<br><br>Edit 3: My wife isn’t going to quit her job. She was going to study for it. <br><br>Edit 4: I didn't ask for this job, they offered it to me.
