My opinion is that you should stay with your wife and make a life together. You can’t throw away 6 years together. Every couple fights and if you leave that does not necessarly mean that you will not hsve arguments with that person. From my point of view, the only thing chaged will be the person. You already know the answer, because you said you two still love each other and want to make it work. Just talk to her about what’s on your mind and try to understand and listen to each other.
