Husband says i abandoned him

A week ago i wrote about snooping and finding out my husband ex emotional affair partner still emails him and he has even sent her money. The bases of their little romance was him “helping” her on hard times. He said he was falling for her because he felt needed with her. He finally ended it with her saying he loved me and wanted to be a family and that what he felt was just a strong care for her well being as a human being. Anyway reading the email from her seemed like she is very comfortable with him and maybe there might not be romance but sounds like he never really cut her off or really wants to. And i have promised him when i find out i would leave him. Well i saw the emails after he left on our yearly family one month long vacation. I was flying out with the kids a day after he left. I landed 3 days ago and i sent him a email that i saw what i saw and i blocked him. He has tried reaching out on instagram and i read the msg and ignored him. He finally called with a different local number which i didn’t know and asked if i wanted to talk, i told him i don’t have anything to say. The phone cut off. He sent me a msg saying i abandoned him in a different country lol, this country is my home. How am i supposed to walk around with him and our kids pretending like he hasn’t betrayed my trust once again. I mean this man recked my heart and soul when he told me he didn’t love me anymore and he wanted out because of this girl. And he expects me to stay and tolerate him talking to her because he says there is no romance and she is actually very nice and that her family respects me and love him as a brother because he “saved her life”. Ive never felt that kind of emotional pain and i wouldn’t wish it on my enemy either. I chose to move forward with him because i loved him and believed that it was just a quarter life crisis on his part and that we can grow and be a even better couple. But he just wont stop talking to these people. Im so confused why he would risk loosing us, me and the kids, ruin this family vacation abroad. We planned the trip for months and he ruined it but says i abandoned him. I told him he needs to fly to that country where the girl lives and do christmas with her family.
