Some updates.
My H and I went to see MC. He told MC he felt unloved for many years and his thought of divorce is on and off for so many years as well. The MC asked us many questions and pointed out what I did in the past shows I loved my H, but maybe his perception is different. Finally my H admitted that I may love him but he claimed that I don't know how to love him. Even I can change the way I love him, he doesn't want to try any more. He said he is in 40s now and he doesn't want to waste his time. He wants to move on :-(
What he didn't say is that there is OW waiting for him...

Any inputs?
