Maintaining a long distance relationship as an expat in Thailand

Wow. I first got to say; If I was working,  had the kids, and still married, I would not let my spouse leave. Let alone live in another country. Especially Thailand.  Where there is no ability for a foreigner to make any kind of living, alone. I could not be happy without seeing or taking care of my children. What quality of life can one have when their heart is somewhere else? I need family to exist. Without a family is like a farmer who grows nothing.
That being said, what are your real options? Use Skype to talk everyday? Learn Thai? Sell something Online? You are going to have to figure out What Makes You Happy. A Hobby? Yoga? Exercise?  Cooking? No matter how you look at it, eventually life will be prison like. I need to take care of my family to be happy.
I have a purpose.
Maybe write a book. Volunteer?
As a man, my roll is to; Provide very important elements to the family; Peace of Mind. Stability. Protection. Dependability. Strength. Kindness. Understanding. Safety, Money, Love. I needed these elements more then anything else.
My world revolves around you.

Short answer.. IMO.... if a man has a significant other. He would not move to Thailand. Thailand is not a place to find big money nor does it offer a place to live long term easily. Its a place of relaxing, retire, or have fun. Its a paradise as a single man looking for life. I do not believe many can have a comfortable apart distance relationship without jealousy , stress, cheating.. Its not suggested to test it. Thailand has many beautiful sights, temptations, and new discoveries. It's best to come to Thailand as an adventure. Without a relationship left behind and have a heart and mind open for a new and better way of life.

When I arrived in Thailand, after a few months I preferred to close my previous relationship.  I did not create the conditions for an obligation to come and see me.  I believe that the question is subjective for everyone and not as objective as the question poses.
