Njgal, the possibility of them getting distracted is there , but it isnt a big one. if they are experiencing a stall time in theri marriage , perhaps friends and family should encourage them to make an effort into working things out.
Unless they have grown apart tremendously , not just physically but emotionally as well, I dont think they will take interest in anyone around them...specially when a person's marriage is in trouble, the last thing they look forward to is to get into another relationship.
Family and friends is involved and is trying their hardest. Everyone is telling them to have a child but they insist until things get better - there is no use of having a baby.
But neither one is willing to let go. He wants to go - so the option is she quits her job and move with him. He won't let this oppurtunity go by and stay with her.
They are both good people but doesn't seem like they want to forgo something to make it work.
