She is overly aggressive
Relationship experts often admit that a woman may be heading out of the door in a relationship when she starts being too defensive at the least opportunity. Partners usually would like to ask for answers when they feel that something isn’t right in the relationship. A woman should be able to calmly respond, but if she becomes overly aggressive, then something may be wrong; she could be hiding things from you. On the contrary, a woman may already be cheating when she becomes extra nice towards you.
