Re: Unsure of next step...
This is another example of love not being enough. Neither of you is bad. But you are wise to question your ability to make it in a marriage with her. This aspect of her personality is as fused to her idendity as her dna. If this is bothersome to you, this is how life will likely be in one form or another all your married life. Some people need to express and talk about their day and troubles and problems and reflect out loud with their partner. This is not bad or good, it is just who they are. Not all of us are equipped to be on the receiving end. To make her try to change that is like holding back flood waters. Yo can do it for a while, but it will win out eventually.
We are who we are and it is good you are considering these important day to day aspects of marriage before making the plunge.
