I'm sorry, sweetie, but that was stupid. A Good man wouldn't have screwed you for his travel and visa. Let alone used you as just an incubator for his spawn. You'd better start getting yourself prepped and ready to go as a single parent. As soon as that kid is weened and house trained, he won't need you anymore...

I suspect this was primarily to obtain a green card on the part of the fiancé. OP, that was foolish and took a significant degree of naivety on your part. But I am very sorry that this happened to you - No one deserves to be treated like that.

OK for real, stop victim-blaming. The thing about these people is they are master manipulators. Suave and attentive, making OP feel like they are the only one for them. They are consummate actors. Then once the trap is closed, reveal their true selves. And they go after those that have low self esteem, family problems, are lonely or alone in the world (no family). OP, I am so sorry you got caught by that trash. if it's possible, can you go to whatever your immigrant regulatory body is and tell them what happened? You may also be able to get your marriage annulled and have him deported. My heart goes out to you and that innocent child. Take care and I hope you find the help you need.
