What should I choose, Life or Nirvana? A little personal story ahead also sorry for the long post...

Story:

Three years back my life was a disaster, I was as far away from Dhamma as possible,   I was into the dark side of modern life. Drowned into money, greed, sex, addictions which inevitably rolled me into stress and depression, but I still had my job. At the time, I was reading one of the books by Thich Nhat Hanh and one evening as I left my office, I sat on a fountain-side watching all the people coming out of the high-rise buildings rushing to catch the tide back home. I had kind of epiphanies moment where I asked what am I doing with this? where is my life going? I felt that I definitely did not want to spend my life climbing the corporate ladder...it was like a terribly dreadful feeling I can't put into words...

So very next day I quit my high paying job, in a few days moved out of the big city and into my parent's house. From there I started seriously reading Buddhism. In a years time, I was way over my addictions at least the alcohol was out. From there I did a couple of 10 day- vipassana retreats and also did a month-long retreat at a Zen monastery. At the end of last year, I was over my anti-depressants tablets and stopped going to a psychiatrist. 

This whole year I spent meditating in Zazen and Vipassana, I have finally to my satisfaction finished reading books. Now I have come to the point that I have known that the Theravada tradition is best suited to me and I am reading Ajahn Brahm's book on Jnanas the third time.

Question:

My life has been changed for better, I don't have a job for three years but I don't have any financial worries or family concerns. I have narrowed down to bare minimum needs and I can possibly live like this till I die. 

But now it seems I want to live in a better way, in the right way according to Dhamma. Instead of getting back to rat race I can live some other kind of way to make money, go find a girl (again), basically get into Samsara. Life seems to have gotten a new meaning if I choose to give it. It will be a repeat of the cycle, just better this time.

OR

I have made some good progress in meditation. If I continue with current focus for this coming year(2019) I am hoping to progress till a nimitta. Also, I have met a normal guy online who has attained Enlightenment, (from his words and actions he looks genuine) so following his example, Nirvana seems like an achievable goal within a human lifetime. 

The problem is that the idea that if I get Nirvana I will not be reborn again seems discouraging. Now life seems like worth living again, although I am very much well versed with suffering. 

So, in the end, my real question is how should I make a choice between Samsara(going back to make money and lay life) and Nirvana(single minded focus on meditation)?
The problem is that the idea that if I get Nirvana I will not be reborn again seems discouraging.

This is a problem because you think that being reborn is good but actually it is suffering. If you want to be reborn in a heavenly realm you should know that these realms are also impermanent and it is much harder to practice the dharma there. And you also have no idea how much you might have suffered in samsara.

In SN 15.3, the Buddha said this.


  "Long have you (repeatedly) experienced the death of a mother. The tears you have shed over the death of a mother while transmigrating &amp; wandering this long, long time — crying &amp; weeping from being joined with what is displeasing, being separated from what is pleasing — are greater than the water in the four great oceans.
  
  "Long have you (repeatedly) experienced the death of a father... the death of a brother... the death of a sister... the death of a son... the death of a daughter... loss with regard to relatives... loss with regard to wealth... loss with regard to disease. The tears you have shed over loss with regard to disease while transmigrating &amp; wandering this long, long time — crying &amp; weeping from being joined with what is displeasing, being separated from what is pleasing — are greater than the water in the four great oceans.
  
  "Why is that? From an inconstruable beginning comes transmigration. A beginning point is not evident, though beings hindered by ignorance and fettered by craving are transmigrating &amp; wandering on. Long have you thus experienced stress, experienced pain, experienced loss, swelling the cemeteries — enough to become disenchanted with all fabricated things, enough to become dispassionate, enough to be released."


If you want to achieve nibanna then practice the noble eight fold path. 


  "Of those, right view is the forerunner. And how is right view the forerunner? In one of right view, right resolve comes into being. In one of right resolve, right speech comes into being. In one of right speech, right action... In one of right action, right livelihood... In one of right livelihood, right effort... In one of right effort, right mindfulness... In one of right mindfulness, right concentration... In one of right concentration, right knowledge... In one of right knowledge, right release comes into being. [4] Thus the learner is endowed with eight factors, and the arahant with ten.


You must also practice the four frames of reference. I’m not going to say how to practice it here but these four frames of reference are not four different exercises. Right mindfulness comes before right concentration so I think you should practice it if you want to achieve nibanna.
