Writer's Fallout Shelter

-If anyone responds to this I would be very grateful.-

I am writing a sequel to a story that I wrote. In the first story one of my lead characters is betrothed, and ends up falling head over heels in love with her betrothed.

But at the end of the first story the character is separated from her betrothed. When she is separated from her betrothed she develops a minor crush on the main character by the time the first book ends.

It kills me, but in the sequel the character learns of her betrothed's murder and yet she has feelings about the main character. I am having A LOT of difficulty writing about how she feels.

I mean the character is devastated, she even loses all her will to live at one point in the plot! I just, don't know how she should show her emotion. I can't really have my character crying constantly and she has a lot to deal with... And, at the same time she has feelings for another character!

I guess what I'm looking for is any advice from anyone about how to deal with this situation.

Thanks
