I've got that vibe too before, she blames it on the village and no date nights, then bf Charlie so no sex for months while telling the Internet this.I feel like she’s been desperate to come back to the UK the whole time and is just using what’s going on over there to persuade Kyle it’s not safe and he has to move to the UK with the kids. Maybe controversial but I get the feeling she doesn’t even like Kyle that much. It’s just convenient that he can father her children and bring in the money.

She got pregnant with no plan B, she'd already had an abortion (no judgement Caroline when you're reading, just fact stating)
So maybe didn't want another or Kyle maybe wanted the baby so gave it a go. I feel he is definitely under pressure to move.
