Am I (F25) being selfish for not wanting my husband to travel?

A little backstory: We travel a lot, often spend summers outside the country, go on a trip a month, camping, hiking, etc. We have spent months on the road before. I love traveling with him, I love the experiences that we have together, I don’t like traveling without him.<br><br>He has decided that he wants to make some money on the side and is going to work as a medical technician for 3 months in a very remote town. I don’t want to go with him. We live in Europe and he has been offered a posting somewhere in the wilderness of Canada, so I am not comfortable with the idea of going there alone without him, especially being a foreigner. I am also not too keen on being alone somewhere isolated for 3 months. He has to travel in January and I have plans in February that I don’t want to give up, so I am planning on joining him for only a month.<br><br>His family is very upset that I want to stay home and think that I should go with him for the entire period. According to them, since I am his wife, I need to follow him and support him. They are very upset with me about this and think that I am being selfish. He is also not thrilled about me staying home and is disappointed, but not being pushy.<br><br>Am I being a bitch by not wanting to go?
