Failed on the 7th day... advice, anyone?

So i joined Nofap more than a week and a half ago and decided to do the 90 day challenge on hardcore mode. I wanted to partake in this challenge not because I was a porn addict or masturbation addict per se, but because I had begun to use sex (in any form) as a way to escape the feelings of loneliness I had for a long time. I'm not saying I would go out and sleep with a bunch of people. I only ever had a few one night stands (and I regret all of them), but they never paved the way for any kind of relationship, which is what I always wanted. I never wanted to start off a relationship or anything like that with sex. I'd REALLY rather just get to know someone first before sleeping with them, but I seem to keep doing the opposite

It gets worse as when I get really horny, I start rationalizing just datng anyone for the sake of having sex. I start settling for qualities/types of people I would never ever want to consider on a thousand years. And I KNOW this is not what either of us would want, and it would be so unfair to my partner to date him for a reason like that (which is the only reason I haven't dated anyone in a long time)

I went into the challegne thinking I was going to accomplish this 90 day goal because I wanted to improve my willpower muscles, but I ended up relapsing 7 days in (PMO). Worse yet, I started falling back into the old habit of contacting guys from before with the intention of getting a booty call (I never let it get that far, but I did end up asking someone out for all the wrong reasons).

I feel really disgusted with myself and disappointed and I don't want to fall into the cycle again. So I'm going to attempt this again and watch myself a lot more closely. If anyone has any advice or tips and tricks about how not to relapse, or even help me wade through this jungle of emotions, I would be very appreciative for the help.
