Do this, Or I wont do this type of Marriage

I am M30 my wife is 26, we have one daughter that I love so much, she is pregnant for our second born. We have been in marraige for 3 years. I need honest advice from people who have been in marriage.

I am from a different tribe and city, so tribe has really not been an issue until when i lost my father (may his sould rest). So went for the funeral, we stayed at home for about 4 months and there was total language barrier, my wife struggled communicating with my family and locals, all my brothers have married our tribe girls. Where I come from, marrying from another tribe is accepted but comes with some challenges including cultural differences, distrust and langauge issues, so my wife experienced all that.

We spent a long time at home and we were not working so we depleted most of our savings. When we finally returned, we were already financially struggling. We struggled for a few days and she decided to go to her home city to talk to her parents, while there, she identified a good business opportunity in this her home city. Just to put it in perspective, let us arrange this places in A-B-C. So my home city is A, we live in another central city call it B and C is her home city, so from A where my family is to B is closer than A to C. So she is finally at C her home city and its far from A our home.

I love my wife much as her ideas, so we sta down to plan about the business. Since we had depleted all our savings, we decided to sell our personal car to raise funds for the business. We did so. She adviced me to move from B to C so that we can be together and run the business, I relocated. So now I am in a her home city, new culture and experiences. She runs the business and I work from home, however the business which is her idea, is not going very well, she tells me that if we get more funds, expand it and make it bigger, it will attract more customers. We sell another property at home and invest it in the business. Now my mum back at home is worried, we are selling properties and I am investing in a place far away from home, she starts to complain that I should at least Invest in city B which is close to home.

After investing everything in this business, its still not working. Recently i got a job offer in my home city which my family has encouraged me to take, but my wife who is now 4 months pregant is not supporting the idea of me moving to my home city to work. She has threatened to terminate the preganancy if i take the offer. I have nother offer in this new city but it is not as good the one in my home city. She argues that if i leave and work at my home city, we will ruin our marraige, she says that her all previous long distance relationship never worked and she fears this wont too. I know she loves me and she supports me but i feel she is controlling me, i am now in a situation; go work there, i terminate the preganancy, stay here we continue with the marriage. I need advice, I cant continue being here because the business is not working, but we cant close it as we hope it will start working with time. Is this a health relationship? Should i just go work and let her do what she wants to? Is she manipulative?
