dm on dating at 20: Everybody is single, so since about 3 percent (-ish) of the population are cluster b, you're fairly safe.
jaded dm on dating at 35 plus: Most of the good ones are long-term married, so the cluster b in the dating pool percentage is way up. Your first job dating is to find out why your date is single. Ask. Then watch and see if actions match words.
dm on actions: Watch them.
dm on words: Trust but verify. Where you can't verify, ask yourself, "What other possible explanations are there?"
dm on people: They tell you what they think sounds most acceptable. Ask yourself, "What's the worst possible reason that they did what they just talked about?" The truth is somewhere between that and their story, usually.
dm on actions again: They treat you just like they've treated every other dating partner, ever. I'm just an average guy. Do their actions match this fact?
Aside: I really am average. In almost every area, I am at the top of the bell-curve, which means I am a really good example of average overall. In other words, I am not exceptional.
dm on love bombing: Run. Now. This isn't healthy and where one red flag is waving, more are hidden by the first. And around the corner. And behind those.
In my view, people do what benefits them. There's Maslow's Hierarchy of Needs: physiological (i.e. air, food, water), safety (e.g. shelter, housing), love, esteem, and self-actualization. Where do I meet a need? Do I want a relationship with someone who needs me at that particular level?
I learned from SI that we train people how to treat us by what we accept. What am I willing to accept? From SI, and SI-related reading, the person who does the most in a relationship has the most to lose. From life, that people value a thing based upon the amount of effort it took to get it. People treat well things that have the bigger investment of their time and effort.
Stuff to think about, but back to your list...
Yes, put the woman with the house actions on the list. I don't bet, but I bet that if she had been a better, easier mark than you were then she'd be the one with this problem now and not you. Also, the friending of the 18 year old cheating partner goes on the list.
Regarding writing vs. typing/phone based list - Writing works for me, then taking a picture and ensuring that pictures are automatically uploaded and backed up. I don't think that there's an especial advantage to writing, though I do think that writing is faster and easier than typing on a phone, so I can think about the list a bit more as I'm writing it. But that's personal for me, down to thumb-typing speed, etc.
Also the art thing probably should go on the list. At first he supported it, now he makes digs at it.
One more for you: He put me on this emotional rollercoaster, damn it!
