oh no. Sounds scary about the levels dropping. You worked so hard to fall pregnant and then all the stress with your partner and now this

I can't get my head around your H. (I'll drop the D, b/c he's not that Darling or Dear lol). Did he think that the IVF wasn't going to be successful? I'm not being rude - I'm genuinely trying to work out why he might be so anti- baby right now. What's your experience of his family like? You don't have to answer anything, by the way. Just typing out aloud.
The only thing I can think of right now is to try and get him to attend a session with you and the counsellor (I can hear him thinking of excuses, right now), but mainly to have somebody to mediate these conversations for both of you. How to work out the logistics if you decide to keep the babies. As much as he thinks he can walk away from all of this, like others have said, the pre-nup may not stand up if he's gone through IVF with you and you're expecting his children. It also sounds like he's not allowing you to talk and it's all on his terms. A bit like the pre-nup.
I work as a psychologist, but I don't provide much couples counselling. I do know that at times, you can invite the partner in for a one-off session to discuss a few things or involve them (especially if you're working with children). There's so many questions. Is the only reason why he's wanting a divorce b/c you are pregnant? He really needs a good kick up the bum! Unfortunately, counsellors can't do that bit (well, not physically, anyway). I'm really sorry for the way that everything's going for you right now. You're doing exceptionally well, under a really really stressful time. Not easy.

Haha my D is stand for " Dumb " lol he was upset when first cycle didnt go thru. He was the one who cheer me up and tell me to be strong to go for my FET cycle. He was the one who tell me I'm sure u will get preg this time.
When we went for a scan at week 7 n found out it twins, he was shocked but didn't say anything about leaving me or not keeping the babies.
After that1 week, he came home from work n said I don't think in ready for kids or be settle down for the rest of my life. " it's just hit me that this is not what I want. When I saw the twins I realize there is no going back "
He said he having a doubt that he will be ready to be with me forever and he doesn't want to have kids if one day he will get up n leave.
His dad left his mum when he is 15-16 yrs old. He said he doesn't want to be like his dad.
" I want a time off for like 2-3 months to figure it out what I want .maybe who know in 6 months ill take u back n we can try to hv baby again" That's what he said


He only want me to go counseling and hope I realize raising two babies in my own is too hard. He didn't want me to go because he think it will help me emotionally with this issue.
