Help with advice or opinion

I need some advice. I have two options and I don't know what to decide.

Here's the context: If you had to choose between going to Europe to meet a guy/girl you've been talking to for a year, and you're already in a relationship but have never met, and you have the first option—that person will pay for your plane tickets and you can stay at their apartment for free—or having that person come to your country to meet you, which is safer? In my case, I'm a 26-year-old woman, I've never traveled to Europe, and I'm from Latin America. He and I have talked about marriage and a serious relationship; he already calls me his girlfriend. We love each other very much, but I don't know what to decide. He can't come see me until May, and that's many months away, but the option of going to Europe alone for the first time to meet a guy I've never seen in person... I don't know if it's a "safe" option. I feel very comfortable with him and I'm not afraid, but I still live with my mom and I know it would be hard for her to understand if I told her I wanted to leave. Because if I'm honest, the idea of ​​going to Europe is more tempting, but my sister advised me that it would be best if he came first.

Now I need help, please! It would really help me to have some options. 🥺🫶🏻
