I'm not sure exactly what your question is, but will give you my 'take' on it as a 12+ year pescatarian.
Some of it's been made easy for me, as I developed lactose intolerance in my early twenties. Cow milk is not an option.
My seafood sources are all wild-caught, otherwise it's plants. My personal spiritual practice doesn't have to do with 'not eating meat' necessarily, it is really about not eating a creature that was forced to have a terrible life. I haven't developed the 'stomach' to eat humanely-raised animal meat, and by this, I mean the enzymes in my stomach. Had those options been more available when I first started out, I might have splurged financially (because humanely-raised food is more expensive) and kept them in the game. I don't know.
For me, I'm very aware that without all the great veggie options, I would likely not be able to support this diet long term. I do have to take supplements, too. We do eat lots of organic, happy hen eggs as a protein, as well as goat's cheeses. My son and husband are never restricted from eating meat, either. This is my choice, not theirs.
If you are trying to feel okay about some choices, consider finding a humane dairy in your area which sells fresh milk products. They do still exist. Look for free-range farmers-- ask around. It may be that you find a great farmer who treats their animals well, is humane at butchering time, and cares about creating a relationship between their customers and their product. You might need to do quite a bit of research, but they are out there.
No one can tell you what should feel right for you. I will likely stay with this diet for the rest of my life, because that's what feels good in my soul. You are very aware of your options and all the considerations one needs to make when feeding a family of growing children. Good luck!
