Repenting!

Hello everyone,
I am going through a depressing phase of my life. I started my no omo journey in 2017 with a great enthusiasm. I achieved the 174 days streak then I relapsed. I started again then relapsed again. Why?? Because I met my ex gf on internet. After few days of chit chat we started sexting. Long video calls of doing sexual activities. I was trapped in that. I forgot my journey,I forgot my achievement and I was into this again. I had to send her p videos so that she get horny. It became my daily routine to wait for her to do all those things again. Unfortunately I was in p again. I started visiting those websites again and in the absence of her my last resort was to masturbate.
It went for about 1 year. Then I started dating my best friend. December 2018 was a great month for me. I had sex with her 5 times and it was great. Lasting for about 25-30 minutes but meanwhile all of this I was deeply involved in porn. After taking a gap of 9 days we met again on January 1 and it was a horrible experience. I was out within a minute. Then she went to another city and I was watching porn movies to fill that void space. My morning started with porn ,my evening ended with porn. We met again on 22nd January and that experience was more horrible than before. I ejaculated the moment I entered into her & after taking a gap of 1 hours I was unable to get the erection. So at that day i decided to start no pmo journey again. we met again on january 25 & experienced the same depressing outcome. Since 22nd Jan I almost have no libido. Feeling like a piece of Dead meat.
My gf doesn't know about this. She expects a lot from me but as of now I feel nothing.
I think I am going through a flatline. The feeling of no libido is weakning me. Now I have a real woman to have a healthy sex life but it's quite depressing for me to not to have sexual desires.
I am anxious, depressed and deeply regretting to indulge in pmo again.
Thanks!
