Guy I just met wants to marry me

Problem/Goal: A college batchmate whom I have no previous encounter with came for vacation here in the PH. Now he wants to make me his wife.

Context: We are both 28 y/o. I am a doctor here sa PH, he is a nurse sa US. Around a month ago, nagkaconnect kami ni batchmate sa facebook when I noticed him liking my stories. Finollow ko sya sa ig since napansin ko dami naming mutual friend. He works in the US. 3 weeks ago, nakabook pala sya ng flight for vacation dito sa pinas so nag-agree kami magmeet pag dating nya dito. Wala akong expectations about the meeting, it was just nice to meet new people sabi ko. We had dinner and a few drinks. We kissed but didn’t have sex since di ako comfortable doing it with someone I just met. The night was great and he’s a nice guy but not my type. Type ko kasi yung mga clean looking chinito, but he has tattoos and ear piercings. He also has alot of exes and body count compared to me (which i am not personally comfortable with). He is the complete opposite of me. Pero I admit sobrang gentleman nya and soft-spoken. Nagulat ako kasi di ko naexperience yun sa previous na mga dinate ko. He told me all his flaws and life experience during college and how it made him mature now na he’s living alone in the US.

He then asked for a second date, and it happened..one thing led to another and the next thing I know, I was meeting his friends and family. Now, he wants to marry me and be with him sa US. Ready naman ako to migrate kasi mag isa lang rin ako dito sa pinas. He knows I’d need to leave my profession here sa pinas and start over doon sa pinas—to which he says he’s willing to support me kung gusto ko ipursue pagiging doctor sa US or magwork as medtech doon(RMT din kasi ako). Gusto ko rin naman ang family nya pero concern ko kasi may pinagaaral pa sya na mga kapatid.

Previous Attempts: I kept asking him if nabibigla lang ba sya and ready na sya magcommit talaga. I said my life here is already comfortable and if mas mahirapan ako doon then I won’t go. But he keeps on assuring me. I told my family about all of this and they have reservations. Nafeel ko narin naman na nice guy, mature, and with provider mindset sya, but I am scared haha. He’s also been researching about how to apply for a dependent visa, about engagement rings, projected cost of the wedding etc etc. He says he still wants to propose to me and willing sya umuwi ulit anytime for that.

Ask ko lang kung may cases ba talaga na ganito na ready na talaga yung guy magpakasal kahit wala pa kaming isang buwan magkakilala? Or baka manic phase nya lang to. 😅 Takot rin ako na baka nilolove bomb lang ako.

EDIT: Pinoy po itong si guy.
