Love, kids see OTHER kids, they see telly programmes, they ask questions.
The one I have to answer is Mummy, why don't we go over to see Granddad in his house?
I can't tell him that my dad married a woman (OW) that banned us from visiting, that we have zero presence in their home, they have pictures of previous pets, but the many, many pics of DS and his cousin are not on public display. HER GC are, her dog is, but not us, and not his GC. I have no idea what to say.
Granddad does at least love DS/DN, he wants to see them, your situation here is different.
You need to think this through, all of it. You are placing this DP at the centre of your universe. that's never a good idea, and not when you are so exposed, both financially and emotionally. Why is your life so pared back?
Where you are going, is there a language you'll need to speak? do you speak it? if not, if you don't make friends too easily here, it's not going to be any easier somewhere forrin.
I wonder if you are running away? it's all so precarious, so romantic against all odds, maybe you are thinking on some level that life is a dream if you go somewhere else?... Not necessarily, it can be your worst nightmare.
i spent 3 years in practical isolation, DS was 6m when we went there. I know how hard life can be when abroad. In the end, I had a friend I would be able to see maybe twice a month, rarely more.
You only really need ONE good friend in life, more is a total gift, a blessing. I've spent over a year with absolutely NO-ONE to call a friend, i would not recommend it.
