My husband filed for divorce after 6 years with his main reason being that "I fight with him too much" and he thinks I will never stop.  Yes, we did fight, but I was trying to communicate with him about very serious issues.  

The problem is now my mind is bombarded with "what if it's all my fault" thoughts and it is throwing me into a deep depression and giving me awful anxiety.  I would very much appreciate some honest feedback.  These are the issues I would argue with him about...

So, my husband, in my opinion, has an overly close relationship with his daughter.  She's 18.  He's been sending her selfies.  Just him smiling, but I think it's so weird.  He doesn't send them to his son.  He doesn't  even send them to me (he used to when we dated, though).  And then she hearts them.  
I have an 18 year old daughter and I don't send her selfies of me, only pictures of us together after an event or something.

so is this weird??  To me it is like what people do when they're dating...send selfies back and forth.  

I've been trying to figure out the disconnect.  The fixation on his past life, his kids fixation on their past life with their parents together.  But many times it's not even them together...it's him and his kids alone.  I overheard him talking to an old friend tonight at a social event...and my husband is saying, "she just filed for divorce, bam, out of the blue, no warning"

They are both seniors and work together.  My husband is making it very difficult.  He hasn't said anything to her, but he's been acting like it's the end of the world to me.  Saying she's making a highe mistake and will ruin her life.
