I've been in a relationship for the last two years, we are in our late 20's and during the last year we have had some talks about future, we have different views for the next five years, she would like to start living together in the next two years or so, getting married and start thinking in kids (right now we are not living together and I haven't agreed to this), but I am more the type of person who always tries to improve, I spend a lot of time studying, trying to keep up to date my skills and to be honest I'm not thinking about marriage or kids right now, what I want is to get a better quality of life, and I think my best shot is getting a job offer in a 1st world class country.I think communication is the key for a relationship to success and I've let her know that she can tell me anything that is bothering her and we can figure out a solution, I'm always relax and I try to avoid conflict whenever is possible.
Now, about her, she is not really the same type of person as me, she likes to spend her time doing other things such as watching series, taking language classes, sometimes she goes to the gym and sharing time with her family (partying, drinking.. etc), but that is pretty much what she does.She is not that interested on studies and knowledge.
She also tends to get angry before start talking about things she doesn't like or simply she doesn't mention them until she is too angry and the discussion already started.
We work at the same place and there was one occasion that I had an offer from a different company in the same country/city and when I let her know about it, her replay was like "mmm... ok", after some days of me talking about it she confessed me that she wouldn't like me to leave the company, what I was expecting was some kind of congratulation, but her attitude was a little bit selfish, I ended up declining this offer for different reasons, so this gives me an idea of what I can expect when I let her know about the new job hunting.
In our last talk I told her about the possibility of me moving to another country in the next years and she told me about kids and marriage, we had a little discussion but at the end she agreed to continue the relationship with the possibility of me leaving the country, I can't blame her or complaint about what she is thinking, I understand that everybody has their own goals, but what I'm pretty sure is that she wasn't very happy with that possibility.
I can't take her with me, moving to a different country implies language barriers, money and you can't take simply someone with you unless you are married.
