We have been abandoned, how do i explain that to a 3 year old

[Redcupcake]

So about 3 weeks ago my husband walked out on me and our three year old boy, there were no relationship troubles I know of it was very unexpected and out of the blue. All I know is he hated my dad and he hates how much time I spend with family.
I spend time with my family when he is at work and every night i am home when he is to make dinner ect, so I never saw this as a problem. I don't know if that's the cause or he met someone else? no idea to be honest.
Anyway he walked out and left the country and moved back to our Mother land without saying goodbye to our son. I have a visa to work and live where I am and my son has been raised here since he was born so I don't want to leave and I don't want to uproot his life.
But how the heck do you explain to a 3 year old (4 in may) that daddy isn't coming home?
please any advice is good advice so far I have just been telling him he is at work because he is so young.

At that age they are very accepting of any information so I think you might as well go with truth that can be built on as and when is appropriate. "Daddy has gone in an aeroplane to X country, here let me show you on the map". I don't think I'd go with "and he isn't ever coming home" at this point, just that you aren't sure how long he is staying there but its going to be quite a while. So you have any contact? Will there be calls/videocalls or has be literally just vanished? It all sounds really tough for you

I agree with pp - keep it simple and don't talk about daddy leaving forever. Just say Daddy has gone to X country and leave it at that. At 3 they don't need a lot of information - they live in the present time, not the future or the past.

I'm sorry for what you are going through, OP.
