From experience, here are few things to note.

1. People hardly change. NEVER forget that. Make peace with it if you can, otherwise, quickly head for the exit.

2. A woman who cannot say sorry or admit wrong is bad enough. Combined with manipulative strategies, you are a disaster waiting to happen.

3. From experience, its very doubtful if she really love you. If she doesn't love you and obviously doesn't respect you enough to apologize, if you end up in marriage, she will abandon you at the slightest difficulty.

Believe me, I am talking from real life experience.

I wish you the best in your decision.
