May be you you can put a break on your delusion of grandeur and get back in touch with reality.
You are nothing but a tiny EU4FAM card holder. Ireland doesn't need you , its you who needs Ireland right now thats why you are here. Ireland and the company are two separate entities and of course if the company needs you they can sponsor a work permit.
Here is my personal experience like they say in India take it or leave
:
I never separated from my spouse but a few time when i came back in the country travelling alone they sometimes asked routine questions: where is your wife , are you still together, where is your address (You are free to lie now. But at that point you wont know if they have the info )
You go a really good response above on what u need to do.
Again nothing may happen in short term you may be fine but its on you and your luck
Good luck.
