Moving around a lot makes it difficult to establish relationships with people that are solid, in my opinion.

I'm just saying this because I live in an area where there are lots of people who move in and out constantly, and the more "nomadic" people don't seem to have any long term friends, or they stay single much longer.

Many people never do find a soulmate, partner or spouse. This is the reality of today's world we live in. Some people will wind up alone. Some will be miserable this way, others will embrace it; and I think a third category will feel somewhere in between.

I agree with what someone above said, you never know if those couples are happy or not. They may seem that way one day, and the next day you find out they are splitting up, or there is abuse going on, or something else.
