Hi Faithie,
I'm from DIS, or BIS but my original due date was august, so I pop in every now and again.
I just read your thread and felt compelled to reply. You seem like you have thought about this a lot.
You deserve to be happy. You need to do what is going to make you happy. It must be heartbreaking to see how little interest your oh has in your LO.
I thi k that if your OH did try to take your LO away, it is classed As international child abduction, and you would be able to fight it every step of the way. Although, if he isn't interested now, perhaps he wouldn't even try to take him away?
I would advise you to speak to someone close, like your mum and dad, so that you get the support your need.
Sending your lots of love, for whatever you decide xxx
