How to pause/resume a song in javafx?

I'm making a playlist based mp3 player using javafx and I got everything working except how to pause/resume a song. I tried simply checking the player.Status()and using that but it didn't work so I stored the time of the song when pause()is clicked, in a Duration pausetime variable and it works that way but only once. What happens is: I click pause(), it works, click play(), it resumes the song but after that the pause button stops doing anything.

Btw I'm using two separate ToggleButton for pause and play because of the style I'm going for.

Here's the part of the code i'm talking about:

public void play(){
    if (player != null){
        player.stop();
    }
    if (pausebutton.isSelected()){
        pausebutton.setSelected(false);            //resume part
        slider.setValue(pausetime.toSeconds());
        play();
    }
    this.player = players.get(i);
    player.setStartTime(pausetime);
    player.play();
    slide(i);
    csong.setText(playlist.get(i).getName());
    player.setOnEndOfMedia(new Runnable(){
        @Override public void run(){
    if (shuffle.isSelected()){
        i = rand.nextInt(players.size() + 1);
    }
    else{
        i++;
    }
    if(loop.isSelected()){
    if (i == players.size()){
        i = 0;
    }}
    list.getSelectionModel().select(i);
    play();
            }
    });
}

public void pause(){
    player.pause();
    pausetime = player.getCurrentTime();
    playbutton.setSelected(false);
}

I have created a very simple mp3 player, which has most (if not all) of the components said above.

It has play and pause toggle buttons, which do work ;)
It has labels updating the time elapsed for the song
It has a sliderbar, which can be used to move forward/backward. It automatically updates on song play.
