<human>: Can you condense the text into three sentences or less?

We have been together since 2010, engaged in 2011, due
to marry in late May. 

I love her very much, and I have been hurt a few times
when we have been apart (due to work/family reasons) 
as she gets very upset and - I feel - she is unable to be apart. 

She is also completely unable to "let things rest" and is fixated on
things making it near impossible to have peace until said
issue is resolved. 

 believe it my career will always result in me needing to be apart, even for just a few days a week. 

But, I don't think I can handle any more of the stress, as it is always I who calms her and tries to bring back the calm. 

I really want her to visit a psychologist at least to address these issues with a 3rd party, but she firmly believes they will only tell her things 
she already knows. I put a LOT of effort into being a "better man", I sought out
advice years back to help me learn how to find inner
peace, and now I hope she might too, but it seems
unlikely. 

I should add: I have addressed the problem multiple times. 
I have an ex, ex and I live in different countries, still on good
terms but will most likely never meet again (we were 
friends not partners). 

Help me know what to do to address this before it is too late.
<bot>: I think I need to postpone/end my wedding plans as I believe my fiancee is unable to handle being apart and also rationally handle stress.
