<human>: Can you condense the text into a few key points?

I met this woman in Thailand, we spent about a month together.  Met up later in Bali for a week.  Met up again in Switzerland, basically cohabitated there for 3 months.  Recently saw her again in Scotland.  These instances occur over an eight month period.  

On this last meetup she said she wants things to be serious, and that we can't keep saying goodbye to eachother.  Basically she laid out that it needs to be all or nothing.  It was tearful.

She is awesome, we get along great, and we have seen some shit side by side.  Throughout the last year I have been having the time of my life and have had (am having) many flings (she knows this).  My plan was to continue this lifestyle and next year I'm going to live in Australia, she could only potentially visit for a short time due to visa restrictions.

If I want to be with her it means rearranging my life.  She is a nomad too, so that part remains, but I would have to cut out Australia and give up on my much loved promiscuity.  Much of our relationship will be long distance, which has failed for me in the past.

I wonder if I don't pursue this now if it will be shut off to me in the future.  She is the only romantic interest I've ever had that can keep up with me and not drive me crazy in the process.

Do I shake up my lifestyle for love?  Do you think I can handle that?  Do both choices lead to potential regret?

These are the questions I ask myself, so I'm asking you.
<bot>: Met woman traveling.  I would have to change my plans and promiscuous lifestyle to be with her.  What do y'all think?
