Some years ago, I met someone on a night out. There was an instant attraction, he ended up coming back to mine and we spent the night together.
I really liked him and hoped I'd see him again, so gave him my number. I didn't take his number, which as it turned out was unfortunate. I never heard from him again, which was disappointing but not the end of the world, these things happen I told myself. However a few weeks later I found out I was pregnant.
I didn't have internet at home at the time and no one had Facebook etc anyway. I knew the rough area where he lived and possibly the pubs he went into (although the one I met him in wasn't his local, he was only there as a one off, as was I, I lived 30ish miles away).I had no one really to talk to about it or be a sounding board - no family and my then friends were all early 20s like me and pretty useless.
So I got on with things on my own, muddled through and never got in touch mainly because it just seemed impossible. My DC asked about their dad as a young child and I gave some information about what he looked like but they never asked more than that.
The older I get, I can't help regretting it. I know of course that he might not have wanted to know, or been a disruptive presence, but part of me feels sad that my child will never know their father and vice versa. I have several friends who have had babies by donor and at least they can provide their children with basic health information and background on their fathers, I can't even do that.
Realistically it's so long ago now that there's nothing I can do about it I don't think? I've not spoken to my DC about it in years, they don't ask and don't seem to need or want to know. I guess that might change in future though especially once they have their own children.
