How long has your son loved abroad?
How many times has he visited his wife and son in his home country?
How often do they keep in touch?
How much longer does he have left?
Your son should be ashamed.
Your dh is already checked out of the marriage and enjoying his single life. Has he always been that selfish?
He demands his wife to travel to him, with a toddler, in a country she might or might not be familiar with. AFTER he has been "bribed" aka relatives offered for him to visit his wife and son.
He doesn't want to call her, he wants her to initiate contact.
How can he be so cruel?
He is only offended she does not want to see him because she is in the same country.
If she wasn't, he wouldn't care.
So he doesn't want to see her or her son, he just wants to call the shots and have her at his beck and call
Their marriage is already doomed.
