<human>: Hi all. So my girlfriend and I, because of work, often have to do distance. We've had our ups and downs but for the most part have been pretty sure of each other, as in marriage eventually etc. 

She has an extremely stressful job apart from me right now and we hardly get to talk, and she recently asked me do I "feel like we are ever getting complacent?" which I took to mean as "do I ever feel like we are settling". 

I've asked her if she feels that way and she has since taken it back, saying she just thought she was feeling that way when really it was impatience because of distance. This is the second time in three years that during distance, she has questioned things like this. Last time she said something like "I think I've outgrown you/that life" but then she took that back within a day too and we are always perfect when not at distance.

Basically, I'm wondering how serious I should take it. I'm the type of person where it's hard to forget things like that, when I myself was so sure of her, how am I supposed to pretend like I don't know that she has had thoughts that she is settling for me? It hurt my feelings for one thing, and it shakes me trust in the relationship overall for another.

Do I just tell her everything is okay, I'm okay, and forget it, letting her take it back since doubt like that is somewhat normal? Or is it not normal and now I'm the one who is with someone who feels that way about me when I don't? What do I do!

Thanks for any responses.

Can you condense the text into three sentences or less?
<bot>: How serious should I take my girlfriend hinting that she might feel she is settling for me, even though she has tried to take it back, and what should I do about it?
