Help!!! Newbie in a mess!

I needed to start writing again. I was on this blog- 2 yrs ago - when my H of 5 yrs suddenly gave me divorce papers. At the time, I was shocked and this blog really helped me work thru a lot of my own pain. But, in the end, he wouldn't budge and he wanted to go thru the divorce, take some time apart, and then see if we could make it work. We don't have any kids and from everything he was doing, I thought he will snap out of it. Stupid me. Believed it. He came back to live with me 6 months after we finalized the D. Lived with me for 8 months - just went thru the motions of day to day living. I should have gotten back on this blog for advice then....anyways, hindsight is 20/20. Jan 1st he left again. 2 weeks ago, I get a call from a women asking who I was and why I was texting her husband. She then apologizes saying that "it must be her pregnancy hormones". I felt like it was a joke. This couldn't possibly be happening. But, it was....
H still says he is confused. HA! How? He states it was impulsive and he doesn't think it will last. I am so crazed in my head right now....a mess. Its over. I know it now.
He says he called a therapist the day all this happened (I found out) cuz he doesn't know what he is doing and now he has hurt me, the only person he has ever really cared about. NOW he gets a therapist? Now what can be done?
I failed this marriage and this relationship so badly. I had him here for 5 months when he said "This is still not working". I said "we need to go to marriage counseling, we need to take a vacation, etc" Every idea I would put up, he found a way to NOT participate.
Now all of a sudden I'm the other woman? It's crazy, he left 6 weeks ago and he got married 3 weeks ago. Sigh. And she is pregnant?!
I am lost. I am so lost.
