<human>: Can you provide a brief overview of the text?

We are in our 30s and been together, on and off, for 3 years.  

More and more, as time goes by, I find us having arguments about issues that he chalks up to differences in our cultural backgrounds. 

One example is I feel he isn't very supportive about some frustrations I have professionally as a woman in a field of science that is almost exclusively male.  I work hard to promote issues relevant to women in science and to promote gender equality. I also struggle with big issues (men treating my like a secretary or a sex-object) and small ones (just feeling lonely for female companionship) regularly.  He argues with me about my experiences and motivations saying that he thinks Americans are too hung up on some fiction that everyone should be or can be equal.  He also thinks Americans people really like to blame their problems on discrimination, but it's just a sort of laziness towards taking responsibility or just sucking it up.  

Another issue that gets into relationship territory is his attitude towards his professional future.  We are both scientists and academics, and (I think) if we don't do some planning, we are going to end-up living the [two-body problem] our whole lives, as we are doing now.  I say that he needs to set some goals so we can make a plan to reach them together.  He says this is an American obsession with "reaching your potential" and doesn't want to do it.  He says, in Latin America, you just do what you do - you don't have big "goals" and plans to "achieve" them.

I find this frustrating and could use some advice from others who have been in a situation like this on how to navigate.

Thanks!
<bot>: BF and I argue often about issues important to me, he chalks it up to cultural differences, not sure how to cross this deadlock.
