I've never been married. At this point in time I am afraid of the horror stories and I am so used to doing what ever the f*** I want when I want that I would not be good at making the compromises that are necessary for a long term relationship.
If you find the right person and you're ready, you'll make those sacrifices without thinking twice. In fact, you probably won't even have to make nearly as many as you might think because the partner that is truly marriage material wouldn't force you to completely sacrifice the things you enjoy doing. If you're with someone who is trying to implement wholesale changes on you then just end it.
