NEED HELP AND ADVICE!!! 25+ years porn addiction

Hi, I am looking for help from the more experienced ones who have passed the Nofap test before me.Sorry for my bad english.
I am 38 years old and discovered porn nearly 25 years ago. I have always been attractive to women, but I have done pmo all the time. I have always viewed women as a sexual object and that is why I cannot have a serious relationship and family. I have had a lot of sexual contacts, but after being with a woman for a few months, she stops attracting me sexually and develops erectile dysfunction towards her, but that does not prevent me from having sexual contact with another and so I constantly change women. For the past few years, I have always felt that I was not living the life I would like, but I never thought it was because of porn.
Last year, I searched the net for my condition and found nofap. I tried a couple of times but failed, however I reduced PMO from 15 per week to 2-3 per week. Unfortunately for the last 2-3 months, I continue to watch porn and masturbate (just edging). Now I know that porn ruin my life, also I have ED ( if I am with same girl more than 3-5 months) and DE.
Unfortunately I broke up with my girlfriend 2 months ago and decided to start nofap again and quit PMO. Now I'm on day 7, I've downloaded a few nofap apps for my phone and computer, I feel like this time it's easier for me to do it right. I don't even think about porn or masturbation. Can I be in something like a flatline? Has anyone had the same symptoms? Тhanks
