What is wrong with me? Libido completly broken?

Hey guys, I would like to apologize first for the bad english. I actually speak German

I'm 21 years old and have actually a big problem..I honestly don't know where to start.
I actually recently broke up with my girlfriend (1 month ago) and now I have enough time for myself and to try Nofap for me. I want to stop with porn because I feel bad all the time when i do it. I watch porn since i'm 14 or 15 maybe almost daily. At this point, I'm already 54 days Porn, Orgams and Sex free. Sometimes I am struggling with erectile dysfunction. Sex with my ex girlfriend was often not possible because of the erectile dysfunction.
Sometimes it worked and there were no problems but then only for one round and once a day.. The thing is.. I try my best to achieve my goal to be the way it was before.

But to be honest, I'm scared. I was at a urologist a year ago because of my problem and he said physically is everything fine with me. But.. I don't know when I changed, I think 2 or 3 years ago.. I can still remember it well. I saw a pretty woman or just thought about sex with her or something else and I was horny as hell.. I haven't had this feeling for a long time. I don't know much about Porn and Nofap but I think it's because of all the porn?.. When I look at a woman now, I don't think much of it. I look them up and down for a moment and nothing more. I had a wet dream a week ago and was dreaming in that night about sex with my ex girlfriend.. I feel a little lost and I'm afraid that none of this will help me. As I said, I'm 54 days of porn, orgasm, and sex free and it's actually not difficult. I think it's because the breakup with my ex-girlfriend was very tough on me and that's why I'm not interested in other women. But i don't know i just think thats the reason. I hope you can help me a bit because I'm really overwhelmed

Best regards

 

Thanks for your post buddy
Of course, a breakup is painful, but I actually didn't feel like that long before the relationship either.
For a year or two maybe more I hardly feel anything when I look at women.
Is it because of my libido? and how can i fix this?

 

To be honest, I recently felt very lost and I didn't had any goals and I didn't know what my future was like.
But that has changed a few weeks ago. I read books every day now. About Personality development and things like that. I feel a lot better now and have actually some goals that i want to work for. But my libido is really bad. Most of the time I don't feel anything when looking at a woman
