<human>: My husband JP and my best friend Grendel are coworkers. They both love me but hate each other, I am always in the middle. Husband does not care because he has tons of girl-friends (he is extremely smart/geeky and doesn't enjoy the company of guys, all the female friends I have are because of him)

When I started dating my husband, he introduced me to Grendel, she didn't like me at the beginning, not because she had feelings for my husband, thats the reaction I always get from girls and I'm used to it. But the longer the time people spend with me the more they start to like my personality. 

We became really good friend, to the point that when I got pregnant, she threw me a baby shower and became my son's godmother.

Now the problems is, my husband likes to "play rough" and can be a jerk to his friends or ignore them when he feels they're being annoying, Grendel is a little bit sassy and when she is on her period she can be scary and a little bit mean, specifically to my husband. 

I guess their fights have been getting out of hand, because 2 days ago I made plans with Grendel  and later that day she cancelled them and told me that JP it's just impossible to deal with, and that she doesn't want to have anything to do with him (including me and my son).

I love them both (obviously I love my husband more) and I want them to get along. But my husband doesn't care, because he has no problem making girl-friends, he tells me that we have enough girl-friends, but to be honest those are his friends, if he is not present, I can feel some disdain coming from them.

How can I make them get along if they don't care for each other?

Just to clarify, they don't have romantic feelings towards each other. She is definitely not his type body/personality wise, and even if she was, he will never go for anyone else.

Can you summarize the given text in a few sentences?
<bot>: SO and best friend work in the same building,  they constantly fight. Best friend has decided to cut us out of her life but SO doesn't give a sh't. I'm heartbroken.
