Husband secret child

I was married to my husband for three months before his ex girlfriend from 10 years ago, messaged me telling me my husband has a child in the country where he’s actually from. My husband didn’t tell me this before we got married and I found out through her. I confronted him and he said he desperately wanted to tell me however he was afraid I’d never be with him or marry him if I found out. Heels 18 when she got pregnant and he was broken up with her at that time and she purposefully got pregnant so he wouldn’t move to the states to study. He however still left. He never keeps in contact with that child nor sends any child support because her now husband has legally adopted this kid. However she still demands my husband to skype him because the kid is 9 and asking who his real dad is and why he doesn’t want to talk to him... my husband is not obligated to talk to him or have anything to do with him since he was technically adopted by her husband. Plus, she got pregnant on purpose to get him to stay in their country. She didn’t want him to move to the US to study. So she acted selfishly and got herself pregnant. So is it right that I forgive my husband because honestly, he was young and this bitch is obviously psycho.

UPDDATE***** yes, as a women, you can get yourself pregnant. She lied to him and said she was on birth control. Later after she got pregnant she told his mom that she lied because she wanted him to stay. So from where I see it, My husband is technically a sperm donor and is not obligated to have anything to do with a son that was conceived out of trickery and ulterior motive. That boy has a father who was there for him since he was two, he doesn’t need to know a biological father who never wanted him. My husband was 18 and she tried to rob him of a future. One that he continued as planned and now has a masters degree and a successful corporate job. Plus I don’t want him in communication with a strangers kid. We have our own kid that he lives very much.

UPDATE #2: for those of you who are saying I’m a bitch for not letting them communicate, my husband himself doesn’t want communication with them and blocks all her calls and her Facebook accounts. She only started contacting him after she saw US get married and have a baby! My husbands point of view is that he doesn’t love the child because he never loved her and he was 17 so he never met the kid cuz he moved to the U.S. right then and he doesn’t even want a connection with the child. He sees it that she just stole his sperm and that’s it. He doesn’t want anything to do with the psycho or her child. And sorry, 9 year olds don’t question who their biological parents are unless you as an adult are telling them things... which I believe is very inappropriate considering his age... and for those of you who are asking if we know what it feels like to grow up without a dad, My husbands dad left him when he was one and never wanted anything to do with him... so my husband did walk in his shoes.
