<human>: We were dating for nearly 3 years.  I will admit he had some reg flags flying, but I was in love with him and I thought we could work through them.  I wasted time (I know, sunk cost thing) but because I had put so much into the relationship, I tended to overlook things more than I should have.  Plus, I'm 36 and I want kids (and so does he) so we were planning to try this year.

Our plan was to purchase a townhome together this summer.  This past month, everything has fallen apart.  He has escalated his temper to what I no longer consider over-lookable.  He twice broke things out of anger (and I have to tell you, he gets mad at *nothing*, but it always gets pinned on me so he has someone to rant at).  This alone made me think we shouldn't move ahead.

But then I find out he's been sexting a young woman that he used to work with.  Her texts were up when I opened the iPad, and he was requesting nudes of her.

I blew up and confronted him, but he blamed everything on me (I put too much stress on him, I am not affectionate enough, I blow things out of proportion).  All insanity.  So I told him we are absolutely through.

I went no contact, but now I am livid.  I want to drive over there and break things.  I am so angry that I used up 3 years of my life on him while he is just a huge jerk.  I am not going to do this, but the anger is just red hot inside of me and it takes everything I have not to call him to scream at him.  I've never had anger issues before and it feels scary and out of control.

How can I stop this toxic anger?  I've never felt so angry at another person in my whole life.  Realizing that this year will not hold a new home, a pregnancy, planning for a wedding, all because he is a selfish prick  -- there are just no words.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Fiance was sexting and will not apologize so I had to go no contact but now I am more angry than I've ever been before
