What do you think

If someone (female)wrote to you on facebook randomly and told you they been with your husband the passed 6 months but knew nothing of you as his wife. Tells you that they are pregnant. Yet, you didnt have your facebook under your real name so , it would have been hard for her to search you because you don't have your husband or any mutal people we know as my friends.This person is a sister of a close friend of his sister's, so that would have been a lie. Your husband also had a phone plan under her name and you guys are still married. This (female) shows up to your house and hits you in the face for no reason and you dont even know her like that, at the time she was claiming she was pregnant. You only know her name and thats it. Your husband claims shes stalking him and blah blah blah. Please I want your honest opinion.

Edit: I also hit her back in self defense !!!
