I don't think that he should go away for a boys trip when your household has needs that aren't being met right now. I don't think you're in the wrong to be upset about it. A lot of people, both men and women, have the idea that any money earned is solely THEIRS and they don't take into consideration the household or the family. I have a friend who's ex was like that. His money was THEIR money, but her money was just hers.

I think that he should and must go, because when men burn out and physically and emotionally relationships fall apart, affairs happen, etc etc. i think he will appreciate you so much more if you can get past this and let him decompress so he can go and make money and be the man you need him to be.
He works every day, when is he suppose to rest? He needs a break from family and career, to connect with his close friend, to remember who he really is without daily stressors. Part of not losing yourself in a relationship is doing things like that.
If you say " no" to this, i really believe he is going to resent it.
This is a major decision you are making here, please try to put your emotions aside and think about what would be good for him as a human being. I know it costs money, but this is something he will remember forever.

I just want to add - i ve done both - work two jobs and SAHM.
In my opinion being SAHM is much better than working two jobs. I ll take being home with kids over work . Work is extremely stressful. No one can fire you from being a mother, no one gives you performance reviews or writes you up for being late.

Oh, and i really, really sympathize with you, i wouldnt like it either, but because i love my SO, i would do it to make him feel happy.

Is partner parent to all of the children? If he has chosen to father these children, he chooses to support them.

If this was an overnight drunken frolic the next town over, I may support the going out situation. But if this is a long weekend say 3 to 4 days out of country? I agree it's a bit extreme.

We only had two little ones and the last thing on my mind was a stag anything. If I had been able to pull that money together, it would have gone to our family needs or some treat for us all. Now the kids are grown, on their own, perhaps a trip might be in order.

The first thing that came to mind when I saw the word STAG was "stag films" and "stag parties", both of which suggest "men behaving badly."

If I were pregnant with my fourth (or even my first) child, I would want the father to be around. Pregnancy puts stress on a marriage, even when the child is wanted. I'm not sure it is a good idea to let him galivant with the boys, because men tend to encourage other men to forget their responsibilities, cheat "just this once", get drunk, and other non-family activities like strippers, call girls, etc.

I may be overly cynical, but I believe the saying: "Men are only as faithful as their options."

@LivingWater, I had not heard the term "stag" in so many years, I thought the same thing. lol!

Thanks for responding it is a 3 day trip in another country I have said I am not happy with his decision if he decides to go but I feel I can't tell him to make the right decision because it is HIS decision if that makes sense. On the response I have had on her I no longer feel like I have behaved irrationally so thanks very much :)
