Welcome, pinkfruity. I totally agree with you re the breast cancer - it's in my family, and when I knew my chances were increased to get it, I started researching, and so much pointed to meat and dairy being bad. The China Study is a good book for raising awareness of the negative impact of meat and dairy in our diets - well worth a read, imo.
There are LOADS of recipe books out there, I wouldn't just want to recommend one! And lots of websites too - I don't think you'll struggle to find recipe ideas. I do have my own website, of course, which I mentioned in my first post, and I am building up vegan recipes there! :) www.veganparent.com
I went from vegetarian (five+ years) to vegan, having not even heard of veganism back then, but I think if I'd have been presented with the facts, I could have done it overnight no problem.
DH went vegan from omni overnight, and found it very easy. Neither of us have ever looked back.
I don't know how people manage in relationships when you have different diets to cater for, as I don't have to face that - I think some vegns are prepared to cook meat/dairy for their families, others won't, so their OH's do their own cooking if they want to eat meat, or the OH's/children eat vegn in the home, and eat meat/dairy when out. I think you have to find your own way, and see what works for you. Best of luck. It's getting easier and easier, far more awareness these days, far more products on shelves, far better labelling, many more fellow vegans (I know loads!). Go for it!
