She wants me to move cities...

My fiance was recently transferred to another city and has asked me to come along because we are to be married in a few months. I don’t want to go because my life is in my city and moving will force me to change everything I know. She says she can wait there until I change my mind but won’t reject the transfer because it is a huge boost for her career. I don’t think she should give up any opportunity for me, but I also wonder if this marriage is doomed, given that we can’t seem to find a way around our first big hurdle. What should I do?
All hurdles can be overcome if there is a will, driven by a desire to make something work. You are both within your rights to do what is best for you, but to make a decision that is good for your future will inevitably demand some compromises or a degree of sacrifice. It is how every hurdle in your path will have to be handled going forward, because that is how two people work together. Start by asking yourselves if personal space, professional goals, or married life is a priority. If you have clear ideas about this, it may help you both re-evaluate what you can or cannot do. If you can’t figure it out, ask for time and test this move out. She may change her mind about the new place, or you may change your mind about holding on to what you know. Either way, make your next decision after being honest with each other about what you want in your lives.

How do I get my mother to stop making my life difficult about my boyfriend? She has problems with everything he does and it’s frustrating because it feels as if she doesn’t want me to be happy.
Try working on better ways of communicating with her. Your mother is entitled to her opinion but, as an adult, you can make your own choices too.
