Is it even worth it?

Hey
I came across your site and it has really made me feel a little bit better.
I am afraid that the NC period will lead my ex to forget about me… I know the NC period is for ME, but I can’t help but feel sad about it.
My ex broke up with me after a year and a half. It’s been 5 days and I feel horrible. I want to get over him so bad…
He really shocked me as it was so out of the blue. We were on a romantic vacation and all of a sudden, he says he is unhappy, wants time for himself and says he doesn’t want a relationship… Had to cry next to him for the whole two hour drive back. We didn’t fight, and for the past few months he said how happy and in love he was. Apparently he had been thinking about breaking up with me for a month… he said our relationship was bad and made him feel pressured. I admit I did talk to him about my wish to move out and potentially saw him doing it with me, to which he would reply that he felt the same way and felt I was the only person he felt comfortable doing it with. Lastly, he said he didn’t love me anymore.
I miss him so much but I know what he did was not right.
I just don’t know if it’s worth me doing this. In my mind I think he won’t want to get back together. He is very stubborn… And is good at hiding and numbing his true emotions.. I am just really not sure what I should do. I’ve done the NC since we broke up ( 5 days ago and 5 days of NC).. I just don’t know what I am doing.
