This whole thread has made my blood run cold.
The complete selfishness of one individual, to get what she wants at any cost, and let's face it, the cost will be to the child if OP conceives.
OP, I don't think you have thought about the child that may be born out of this at all. This is all about you, what you want, how you want to go about it and what you will do to get what you want.
My mind sees a child who is not loved by one of their parents, because you chose to conceive with someone who you know is a selfish man who is only interested in his own needs.
When you are having these ONS's and putting yourself at risk time and time again, where is your other child?
Certainly not in your thoughts when you are risking your health and even your life over and over and over again in your desperate quest to have another child. Will you stop putting your health at risk then?
I wish women such as you would stop for one minute and think, really think about the risks you are taking. Your child may actually want to know their father, they may actually want a relationship with their father, yet you have robbed them of that opportunity before they were even conceived. Your child will probably want to grow up with a mother who loves them, not a mother who has contracted debilitating diseases or worse still dies due to not protecting herself.
If you have the money to support a child, why on gods green earth wouldn't you just use a bloody sperm donor? To protect your health?
Your DC are highly likely to only have one parent from the word go anyway, yet you are putting your life at risk to fulfil a need that can be fulfilled in a much safer way. It makes no sense.
Selfish and irresponsible, the pair of you.
