Three Month Downward Spiral After First Relapse... Seeking Advice / Rant

A few months ago I had achieved my first 60 day streak and was feeling pretty good about myself despite always being horny AF. During the past year I have been going through a brutal divorce which eventually caused me to relapse due to the stress of the situation.

My relapse started with just a MO session and I was surprised how sensitive I was. I am pretty sure my PE issues were cured or close to it. After that came the chaser effects and I eventually caved into PMO and it just got worse. From once a day to eight to ten times a day. The trigger was boredom, depression, loneliness, divorce guilt... I used it whatever chance I got to forgot about my problems for even a few moments. Despite trying to get back to nofap, I can't last more than a few days at a time.

Now a few months later, my PE issues have come back worse than ever. Even with porn it takes a lot of effort and life is just overall very dull. I've gained a few pounds because I try to fill the void I feel with porn and sweets. Neither of which actually bring me any happiness compared to when I was into my 30 day streak. I'm still trying but I keep failing because I rationalize that I will probably not date for a few years minimum. Which is where I need advice.

Now my divorce is over my situation has changed and that will prevent me from dating for a few years. I have majority custody of two young kids who are in pre-school. Other than 3 hours in the morning, I am a full time single dad which I usually need to spend either working, buying groceries or other dad related duties.
Until the kids are a little older, I don't think I will have the time or patience to date. I am increasingly lonely and don't have anyone to talk to or connect with. This is why I keep going back to porn because despite the other benefits of NoFap, the main reason I do it is to reverse the PE issues.

After a few days, I start to rationalize that my sex life is over for a few years so why add more stress to my life with NoFap. Although I know it is just my brain playing tricks on me it still gets me every time.

So...
1) Should I forget dating completely until my kids are at least a few years older (8 and 5 right now). If yes, how can I motivate myself to do NoFap when it doesn't really matter if I have PE because of above.
2) I feel like I'm being selfish but I have not had sex in nearly 18 months with 4 of those months in NOFAP PMO. What other alternatives are there? I'm very close to caving and getting a escort just to get focused and get my mind on more important things.
