Communication issue with my wife

My wife is 25 weeks pregnant and was just recently diagnosed with Gestational diabetes(GD). We both have some knowledge about GD like for example it is conmon in pregnant woman and that it will go away after pregnancy.

However , still i was anxious and i did some googling and call our gynae to ask about the risk and what are the things we should do about gd.

I told my wife about the risk of gd during and after pregnancy . One of it was the high risk of developing diabetes especially.My father in law has diabetes and this make her a high risk group for diabetes all the more she has GD now. My intentions were to let her know about it so that she is aware and in future we have to watch out diet.

Perhaps is the way that i bring my message across. However she think that i am being unnecessary reacting and that she thinks that i am telling her that she will get diabetes.

I explain to her that was not my intention and what i wanted was just to let her know that even though GD will go away but it also means that risk of having diabetes in future is high also.

I apologise for not communicating and i tried to coax her. But she say i was being fake. I am feeling hurt and angry. Was i wrong to show my concern in this manner. When it comes to such situations , i feel that there is no trust. Our love bank seems to be on a negative credit that for such situation, she would seem my concern as faking it.

Sometimes i feel like ending the marriage. The thing that is holding me back is her pregnancy
