No, she(!) is creating life, in her body - and that itself will take a considerable amount of energy from her. He is just a donor, he doesn't want to be a dad and it will cost him nothing!

Btw. he is profiting enormously from her help with the green card and living on her expenses. He is in so. much. debt. to her, that giving her his sperm should be the least he can do for her, so that she can enrich her life as well, like he does with her help so nonchalantly and brazen without giving anything back to her, at least so far.

The ignorant answers, that OP got in the aita thread, were shameful and undeserved.

That child will know it was wished for and his donor was there to help its mom. A child needs loving people around them (at least one, in this case their mom), not necessarily the donor
