Thinking about marrying a woman with ADHD

I am new to all of this.  I am in a relationship with a woman who has ADHD. I never really had a clue what that meant.  We are talking about marriage. From reading this forum I see that certain issues seem to be constant.  Such as infidelity, lying, anger and communication. I want to see if we can make it.  What are some good strategies? I saw one post about having the right mindset, What else can I do to understand her needs?  She really means a lot to me and at the end of the day I need to know I am doing all I can for her and us.
