Please help save my life

So, we are Paulo and Rafaele, he is of Portuguese nationality and she of Brazilian nationality, currently she lives in Portugal with her parents, niece and boyfriend, we are 23 and 20 years old
The problem encompasses me, Paul,
My family is currently living in France, I live in Rafaele's house with her parents and niece,
I've been exhausted for the last 3 months, I can't get a job, she hasn't seen a home yet, and it's becoming too complicated for her parents, who also raise a 6 year old who started school this year,
I was called to go to France for my family, they get a job and a house for us to rent and live in,
But as she is of Brazilian nationality makes everything complicated
One option is that we get married, we both want it, we love each other and we have plans for a future,
Getting married is on the table, so she will have the same rights as any Portuguese or European citizen, otherwise she risks being deported to Brazil without being able to return within 5 years, so we really want to get married,
And there's the price of the ticket that we don't have the money to pay for it either, so we decided to ask for your help now, because in mid-November it's when the tickets are cheaper,
The wedding plus tickets have an average cost of 1400 euros about can pay here or directly on my PayPal https://www.paypal.me/pauloreis10
Thanks in advance for all the help possible any penny is a gift, if we do not get the value her parents said they would try to help with the rest, thank you everyone, I know it is not easy, never thought to be on this side, but I learned that without others we are nothing thank you from the heart
