My husband and I lived together for about year before we got married.  We moved in together after getting engaged, mostly to save money by not maintaining two places of residence since we were together all of the time anyway.  And I have to say there was certainly an adjustment period of getting used to each other's little habits.  lol !!  But here we are 18 years later and still going strong where most of our friends who married around the same time and did not live together are divorced.

 

Does that mean only people who live together can have a healthy and happy marraige?  I would say the answer is no but your chances of succeeding are greater, in my opinion, if you get to know someone down to all their dirty little secrets before you legally bind yourself to them.

 

Just me 2 cents
