I felt moved to comment here. My mother is a preacher and I, though no longer Christian, am a spiritual person who believes in most Christian values and remained a virgin until her wedding night at 27.
My advice, for what it's worth, is that if having a child is important to your happiness, don't wait. Men come and go (my husband was abusive and I divorced him five years ago) and the right time to meet a husband will come. Conception will not wait and your fertile years are precious. The right man will love and cherish both you and the child, and he may even have children of his own to contribute to the big happy family.
We all grow up with the dream of having children inside a happy marriage and it is the hardest thing in the world to step outside that dream. It takes a very special type of courage that only we, as women, possess.
There will be criticism and judgement. The world hasn't yet caught up to the progressive women who make this difficult choice. But everyone I know who has ever had a child complains bitterly about the child's behaviour or the fact that they get no sleep and all the thousand little annoyances they put up with every day... but they always end with 'but I wouldn't change it for the world'.
I'm just starting on this difficult journey myself and have just had my first home insemination. Also writing a book about the experience.
I wish you joy whatever you choose.
P.S. Jesus was kind of a donor baby too
