5mo pregnant H wants divorce or to see other women

[Mom22]

Today he said (by imessage) that he just doesnt want to nor is able to put anymore energy in this relationship. And he is sorry because he knows I see it and it is hard for me. I replied its not that hard for me anymore, but its difficult to see him struggle with himself. And that Im still willing to work on us but he has to weigh what his family is worth versus his freedom. Its up to him. And lets try to make it pleasant when we re together (like tonight when we go to a dance show he booked a few weeks ago) and see what happens.
I also booked a house viewing (my first) in my calender (which notifies him automatically). And asked to borrow his car for it.
I ve requested more viewings and advice about a good mortgage advisor from my friend. Im now preparing a 180-exit.
Im doing ok today but it remains hard. I want my kids to have a family but a MLC can take years. I dont want yo be on hold that long. Its been 4.5mo since the affair ended and things have not improved.
