BH, It would depend on what you are thinking. Many women take vacation with their mothers while the men stay home continuing their regular routine work and Kolel. There is nothing wrong with that and that should have no negative effect on anyones marriage. I don’t see why you would think it does. I don’t think that men taking Las Vegas or AC vacations are good for anyone’s marriage. However, when men go to Meron for 3 days for Lag B’omer, as long as it is OK with the wife, and it is ok with the finances, for brachas, etc. I don’t think that should be an issue either. That is what I am talking about in a strong marriage. Things that are thought out and worked out.
I don’t give free passes. Husbands and Wives have to put each other at the top of their priority lists and not let anyone or anything get between them. Neither family or friends; and vacations with friends to get away from spouses is not my idea of vacations that help marriages. But when a husband realizes that the wife who supports him and works so hard needs a vacation and she goes on vacation with her mom who can help her with the kids, or even watches some of the kids while she takes some of the kids, that strengthens a marriage because it shows hakaros hatov. When a husband and wife decide that HE should go to Meron because they need the Brachos and they save the money for him to do that, that shows trust and emunah in the husband and that strengthens a marriage. He is going for the purpose of helping the marriage and not fooling around with his friends.
