jobless
The next time you get the chance, say Shabbos, have a real serious heart to heart with him. Explain that you are lonely and tell him that you dont want him working such late hours. Try to work something out where he cuts back on the hours. Maybe theres even stuff you can help him with so he can come home earlier who knows?
You are his wife you have every right to his companionship.
There are guys that get caught in destructive patterns be it work related or time wasting or other things. You need to find out whats really going on and the only way to do that is have a serious long talk about it. Ask the questions that need to be asked. Feel out his answers. See if he is being evasive. There must be some reason why he is out so late and you have to get to the bottom of it. Is he a workaholic? Find out. Does he maybe push off his work to the last minute? Find out. Maybe he isnt so productive at work and thats why he has to stay extra to finish up. Whatever it is speak to him about it in a nice sensitive way, non confrontational and try to get to the bottom of it. Being at work until after 1 on a regular basis is not so normal unless the guy is extremely driven and is going for something (partner) but if thats what he wants and its important to him, dont expect him to throw his plans out the window.
