After an argument while driving she pulled over and told me to get out. This is norm for her because she's done it before a few times Ofcourse I didn't. The argument was because I yelled at her regarding the way she should go and she has a lot of anxiety about not using a gps and gets scared if she can't see the route. After she calmed down I offered to drive home , (she is 36 weeks pregnant) she didn't let me and drove home. After on the highway she asked why she was going this way I said because you wanted to go straight home. She slammed the brakes on the highway going 120 km and went from the fast lane all the way across the highway to the off ramp. Hitting me in the arm telling me don't touch me and she can't do this. I was not touching her at all didn't say anything and thought holy fuck I hope nothing happens. We were allokay but she was so embarrassed and upset she might of scared the baby. We could of easily had a huge accident and who knows what the consequences were. I didn't let her drive home and am totally shocked she did this. That is life and death situations I know hormones make you do crazy shit but has anyone else experienced this. I don't know if I can continue in this relationship, if she did this I don't know what else she's capable of. She apologized and cried for hours and all of that but she still did it. I'm so confused and stressed, I love her but I just don't know.
