HR had asked, if samsara still exists if I get out of it. Yes , samsara will continue to exist as long as sentient beings continue to be entangled in the web of deceptive pleasures of samsara and not recognize that contaminated happiness is essentially suffering. What we enjoy as a pleasure , for instance, taking a holiday, has the seeds of unhappiness. For one thing it is fleeting and for another, if we have a surfeit of a pleasurable thing, it becomes boring and discontent and unhappiness sets in again.
However, we continue to be deceived by even the momentary 'pleasures' of samsara and see it as happiness. When we become discontented with one type of pleasure , we go chasing after another and so on endlessly. Hence how can we then break out of samsara unless we see through the deception and recognize true suffering and its origin? Hence , though now and again a being recognizes that what they experience in samsara is nothing but suffering and then develops a yearning to be free of samsara, most of the time beings prefer to stay in samsara and continue to enjoy its deceptive pleasures. So samsara will always be there until all beings accept, realize and practice Lord Buddha's Four Noble Truths and overcome the three poisons of ignorance, attachment and aversion.
