In addition to the excellent links given above, you might want to have a look at a series of blog posts by Bhikkhu Cintita, titled .
I also just picked up by Bhikkhu Basnagoda Rahula, and am finding it a good read.
It seems clear to me that Buddhist teachings can serve as a guidepost for a happy and healthy lay life. The more complicated question, for me, is how deeply one can go in meditation practice and in cultivating Dhamma insights while still sustaining a marriage, family, career, etc.
If you're able to develop deep jhana states you might get to the point where you don't want to return to the world of ordinary sense pleasures. If you get good enough at "knocking out the hindrances" you might end up abandoning altogether, which could make it hard to stay married...or pay your mortgage. If you contemplate the Four Noble Truths deeply enough, you may find yourself wanting to ordain.
Being a fairly worldly person myself, I don't pretend to have the answers to these questions -- I often ponder them, and am always interested to hear what experienced meditators (who are also married householders) have to say. My own meditation practice is fairly limited -- at best, 20 minutes of anapanasati a few times a week -- so I don't expect to be riding waves of jhana bliss, although I have experienced some very nice states. The Buddha appears to have recommended a certain amount of meditation for laypeople, but there could be an argument that the really advanced meditative attainments are better suited for monastics or those who are in a position to detach from worldly life to a great degree.
I practice what I would describe as "appropriate renunciation" -- i.e.letting go to the extent that it doesn't clash with my social/familial/spousal obligations and personal goals which I would like to accomplish. There is a lot that any of us can do to simplify our lives and reduce our habit of grasping. Perfecting the five precepts is a potentially lifelong task -- for some of us at least!
FWIW. my advice (which is the advice I give myself) is to try to clarify what your goals are, both in life and in Buddhist practice, and use these to shape your decisions.
