Lottie I am so sorry about your experiences as a child and can completely see why this would make you want to feel very secure before bringing children into the world. This is, of course, your own choice and you are totally entitled to it.
Can I suggest that you and others, PiazzaDelPoppolo, Dinosaurus86, FreeNiki and others who are thinking about these issues' consider looking into egg freezing. The age of the egg is the biggest factor in fertility so freezing your eggs couple be helpful.
I think whippetwoman has a fabuluos idea, "... get fit and possibly meet someone then check out your local climbing club. The vast majority of climbers are men of all ages. You can start as a complete beginner with any weight or fitness level. I know so many people that met each other through climbing that it's unreal."
I have to say that I agree with Whippetwoman, "Google your local climbing club now!"
lottielonsdale "I don't carry weight well at all. I look quite nice when slimmer but I've got tiny features that get lost in fat easily." Please focus on the features that do look good.
I really wonder if you need to look into some confidence related stuff and assertiveness to help you. It is totally understandable in our current culture that women focus too much on their looks, but look at most couples, neither party is necessarily favulous! There is so much more than just how you look.
Laura2507 congratulations on your pregnancy.
