<human>: So we had a fight last night where we were both talking about things we wanted each other to work on and she told me I'm a wimp. Mainly because I don't stand up for myself a lot when we fight. This is because she gets quite hostile, and last time we fought and i fought back, she almost left. She doesn't back down easily and fights just go on and on until someone concedes. Because she's pregnant and i hate fighting, it's usually me. But then I spend the following days miserable because of it

I've always been a sensitive guy and maybe I'm not as manly as others but that's just me. I don't want to fight with her because she will just get angry and leave or break up with me. But at the same time, me backing down is making her think I'm weak. 

How can I balance being a caring boyfriend with the type of strength she wants without having her leave me next time we fight?

Condense the text into a few key points
<bot>: gf wants me to be stronger and less of a wimp but if i stand up for myself, i fear she will leave.
