My situation was a bit different in that DH and I were already married, but we'd only been married about 6 weeks when I fell pg. We'd already discussed babies and DH wanted to wait at least a year and I didn't and it caused a bit of tension that we couldn't resolve it. SO when I realised I might be pg, he was going along with things but I think he thought that I wasn't and he was being OK with it because he thought that it wasn't something he had to deal with for real ITMS. When it turned out that I was pg and I told him, he just turned so cold towards me and it was like he blamed me for deliberately getting pg, even though I hadn't. The reaction I got to telling him that I was pg was 'no you're not'. We didn't speak for close to a week, then things were really strained for another few months. We didnt' even have sex it was that bad. It was the hardest period of our relationship and I was devastated because it should have been so much different to what it was kwim? He never came to a single appointment with me during the pg and basically didn't even want to know about it - didn't care when I started buying things and hated talking about it with other people if it came up in conversation. I felt so ripped off that I didn't get that happy experience of a partner who was involved in it all. BUT when I was about 7-8 months pg he did start to warm to the idea and talking about names. In reflection, I think his reaction was because he just didn't feel ready to become a parent yet so he was freaking out about it all and just couldn't tell me. When the time came and I went into labour, I couldn't have asked for a more supportive or attentive husband and he came through for me when I needed him to the most. It still took a while for him to get used to being a Dad, but eventually he realised it was fine. Things were much better the second time round when we decided to have our second bub and he was much more involved in it all. Clearly it turned out OK for us because we have 4 kids and will celebrate 12 years of marriage this year.

I completely understand how your sister feels right now, and even though I was never ever pressured to seek a termination or threatened that he would leave. The emotional disconnection was the same though I think that this is just a knee-jerk reaction from him, because after all, if it was truly a religion/cultural thing, then he wouldn't have been having a sexual relationship before marriage nor would he be advocating for a termination. I think she just needs to give him time as the poor bugger is probably freaking out about how to tell his parents, especially if they aren't keen on them even being together. I hope it all works out for the best for her
