<human>: First, a bit of backstory.  My wife and I have been married for a little over a year.  We had a very short relationship before getting married, but we had known each other for many years.

My wife has two young boys from a previous marriage.  The boy's biological father is still in the picture and my wife has issues with him frequently.  These often spill over and affect the relationship between my wife and myself.

Last night, my wife told in a text message that she no longer trusts me and she is "done" with our relationship. The reason that she does not trust me is because she feels like she has to put too much effort into getting me to talk about certain things, mainly issues related to my ex-wife.

I want to be open with my wife, but sometimes her method of communicating comes across as harsh to me and I become defensive.  I am also often slow to bring up things that I know she will want to hear about.

She tends to view these things as me being dishonest, hence, her lack of trust.

What can I do to save this?  I love my wife very much and I want to be a good husband.

Can you condense the text into three sentences or less?
<bot>: I sometimes have a hard time discussing things with my wife.  She views this as me being dishonest and has caused her to lose trust in me.  What can I do?
