A break from social media?

Okay so today, a girl and I got into on Facebook. The issue between us didn't start on Facebook. I just basically called her out, after she messaged me all crazy then blocked my messages. Someone had told me she was saying things about me that's why I did it. I'm pregnant, I know I shouldn't try to fight but I was so so mad. See this why I don't like her: 1. She keeps sleeping with my exs. 2. She calls my a liar about her ex bf. (I slept with her guy, I didn't know they was together but I still told her about it) 3. She was assuming I was talking to my ex again, which is her new "boo" which is so funny cause he has 3 "boo's". Anyways i blocked her and deleted the status. This girl hangs out with couple of my family members. My question is it best to take a break from social media? I haven't been on for about 6 hours. What do y'all think? Any comments are acceptable.
