it seems to be like she is just making an excuse to break up
with you. Some girls are like that, but not all.
But I do agree with the fact that communication is very important.
if there is no proper communication of the same wavelength, then it
is going to be really hard to resolve problems and iron out little
differences and that will lead to the breakdown of the
relationship.
For me, if I really care about making the r/s work, I will do
whatever I can to overcome the communication barrier. I am in a 7
month r/s and I am currently facing this problem. It is very
frustrating. Despite all the efforts, things are still as it
stands. So maybe in this case, it's better to seperate.
All I can say is, if she doesn't even want to compromise and give
you time to workthings out, then maybe she wasn't serious at all in
the first place. you can do without a girl like that.
So cheer up!
