My husband is not ready for the second baby... I don't know how i should bring it up

I'm actually enrolled to come back to university next month. I don't know how I should bring it up...

Today I found out I'm pregnant. This is unplanned. I'm very happy but at the same time I don't know how to face it.

I have a 3 years old boy. Ive enrolled to come back to university this March. My husband has just used all the savings to invest in a car business with his friend. And now we have zero savings left.

We only have a house which we are living in and we plan to sell it next month. The reason for selling is to get money to buy a house near my uni. The uni is in a different city (400km away from my current home). At the beginning I plan to stay with my mom in law. Her house is 10 Min away from uni. She's very nice to me but my step-father in law is very strict. He also doesn't want anyone else to live in his house.

Back to pregnancy topic, I don't know how to tell them. I'm jealous of those who have exciting pregnancy announcements... My husband loves me and I know he will accept it eventually but I'm scared to see his reaction... Just like the first one, he walked away sadly after I announced. It was like a nightmare how he treated me during the first pregnancy. All the bad memories came back. I'm so scared to face it again.

About my mom in law, my prediction is that she will ask me not to go to uni and wait another 2,3 years perhaps. I think I can't wait any longer and I want to give it a try.

After the first pregnancy I experienced depression for nearly 2 years. It took me so long to get over it. I really want to come back to uni now. But I don't know how to tell them. Just like other women I want to scream out, I feel over the moon, I want to share the happiness with my family, I want to be spoiled. But again I'm upset and confused and worried. There is a bunch of mixed feelings inside of me right now.

Just like the first pregnancy, this is also unplanned. I took pills regularly and I still got pregnant. How should I bring it up? I'm so scared to even just think about how they will react especially my husband.

I want to hear "congratulations", not "why? How come? How how and how, and blames....

I'm so scared to think about it. No matter what my baby deserved to be welcomed.

I need your advice. I have no one to share with and talk to. How should I bring it up to them?
