I personally would not want to vacation separate from my spouse, I would always want to be with her and have a functional relationship, if there are problems in the relationship to the point that you're going to vacation separately you have more problems than just separate vacations...
well the way i see it, if you are married, then i would find it that they may also love someone else. i would just ask them if they were seeing someone else during vacation, but don't ask it straight, ease into it so they're not for sure whats going on
I vacation without my husband frequently. On our next vacation I am heading down early. My husband gets a bit bored around my friends so I get to visit with them and he isn't bored. As long as you trust each other it is a good idea to get away from each other for a bit. I've been married for 16 years and we do thing together on the weekends, so we spend time together.
Going on vacation WITHOUT your significant other is a recipe for disaster. Your girlfriend or wife needs to know she can't have a healthy relationship with someone and still be able to go spend time with another male. Be a man and tell her it's over. It may hurt to leave the one you love, but it'll hurt a lot less than the pain you'll endure if you stay with her
Depending on who there with if your spouse is alone or with friends or family then sure thats fine and you shouldn't worry but if its with ex boyfriends and one guy or a whole bunch of guys then you should worry because the only guy your spouse should want to go on trips are with you and the family or all girl friends but it depends if she hasnt gave you a reason to not trust her then dont worry and just trust her she would have never done the right things and came all this way to fail a good person like you .
It could go both ways, unfortunately. You could both see how much it sucks to be without each other and there's also the option of one or both of you realizing you don't want/need the other. Sorry dude.
