ExH lives overseas where our children were born.
I live in home country with our kids.
He was unfaithful multiple times, travelled a lot for work, used prostitutes etc, was emotionally abusive, and threatened to always take kids from me after we separated. (living in Shariah Law country, where that was totally doable).
Since back in home country, I have said that he can have whatever access he needs and wants to the kids, but he never skypes or calls, just takes them on a two week holiday (usually when their birthdays are) and Christmas. He has no input or care about their day to day lives, and I never get a break, except when they are away with him.
Came back to home country 4 years ago. I have got on with life, but it hasn't been easy, have had breast cancer and dealt with all the treatment for that and left over side effects, and now work full time, study full time and raise the kids 100% by myself. He totally amped up divorce proceedings the day after I told him about my cancer diagnosis. I would go to chemo and then go to my lawyer, he really dug in deep, when he'd shown no interest in proceeding previously.
During chemo, when he was on holiday with the kids, I asked him to have the kids an extra night so that it would make treatment logistics easier, he said no, and spent an extra four days at fancy resort with his girlfriend.
Girlfriend has no become wife through Shariah marriage, not marriage as per our home country.
They have all just been overseas in a separate country on holidays with the kids. The kids were home for a day or so, and said, 'oh yeah, we forgot, 'Mrs ExH' has got out baby sibling in her tummy'.
I had seen him twice at airport handovers, no mention of pregnancy, I asked him plans for holidays in next few months - no mention of pregnancy. I said that it really wasn't great for the kids to pop up two weeks every year and then have no contact and would he like to set a regular time once a week/month etc, to skype and I would dedicate that time to a call from him to the kids. He replied 'nup'.
I texted and asked if the kids had it right about pregnancy and then when he confirmed, I sent congratulations and regards to him and new missus.
Since I found out I have just gone into a massive spiral mentally. It has brought back all the terrible things he did when I was pregnant and how he treated me when I was either pregnant or with very young babies, until I left. He was despicable.
I don't want him back or anything like that, but I am just so far down, that a family member asked if I was suicidal and I honestly said yes, although I wouldn't do that to my kids or parents. I have thought about it though.
What do I do, and why am i feeling so bad, when usually i am either totally ambivalent towards him or can have a laugh at the stupid antics he still pulls.
I just feel like I can not take any more of this life and the hard stuff it throws at me.
