While there is some credence to "you can't truly learn to live another until you learn to love yourself", I think we king as you approach a relationship with the right mindset you don't have to love yourself / be happy. Right mindset being the operative word.
Anecdotal, but back when my depression was even worse I approached them as a "if I can't be happy I want to dump 110% of myself into the relationship to make my partner happy". It doesn't take alot to understand why that's such a bad approach. As long as you find someone who you can trust with your weaknesses and be trusted with theirs, maintain a open line of communication, and generally be comfortable around I don't see why not.
My first impression from the adhesion issue (which doesn't appear to be the main issue of this post) is that you may need to clean your build plate. But considering it was relatively good as it is, I assume you did and the few spots may just be accidental touches to the surface. In either case, their guide is here: https://wiki.bambulab.com/en/filament-acc/acc/pei-plate-clean-guide
As for the extrusion issue - considering the apparent randomness of it my guess would be either an issue with the filament or a partial clog.
