Ignore Ihadacrush! Appalling attitude, perspective and advice. (Ihadacrush do you even have kids?!) flattered my arse!
It is COMPLETELY NORMAL to not be very interested in sex when you're only 4 MONTHS postpartum, quite likely knackered, maybe breastfeeding (which affects hormones), possibly still sore, feeling "touched out" and unappreciated.
His actions and attitude aren't just crass & selfish they're abusive! Nobody should be pressurised or coerced into sex!
"He's only nice to me when he wants sex." Leave him! He's abusive and doesn't care for you or the children.

"To be frank,he acts like a sex pest." Not like one he IS one! He's actually something much worse but I'm not sure you're ready to face that yet.
"See the cup of tea video about consent (link, someone?). You are being assaulted"

"Tbh when he's away, it,'s bliss!" Seriously leave this utterly useless, selfish, abusive bastard ASAP!
I'm would hope if you contact the british consulate and explain you are a British citizen who is a victim of DV/DA

Do you genuinely have no family or friends in uk or have you simply lost contact due to your relationship? If the latter then I'm sure any family or old friends you contact and tell them what's happening will help in any way they can.
Call your mum! Even if she says "I told you so" it's a small price to pay to get help.
If I were your mum, that would be the last thing on my mind.' My focus would be on getting my dd and dgc the hell away from him!
"And if I tried to leave rbe country, all hell would break loose!" You plan it and you don't even HINT to him what you're doing!
If you're in the EU and have savings and the children have passports I'd recommend you plan to leave the very next time he goes away with work.
"Looks so bad written down :("
Because it IS bad, it's awful. It's not just you he's abusing it's the children too.
Unless your mum is also abusive I think you need to consider that may be your best option for now. Even if just a temporary measure.
