Honestly, I have always been of the belief that this aspect of treatment is completely up to you. My thinking is, if you’re wondering, you may as well just try it out. Premarital counseling doesn’t have to end a certain amount of time ahead of the wedding, nor does it have to end once a couple gets married (it just evolves into “marriage counseling”). In other words, worst case scenario, starting counseling “too soon” just means you figure everything out well before the wedding… which is still a good thing.
