That’s pretty hasty. Be very cautious. You actually have no idea who this person is. If it were up to me, I’d say drop it right now.

The idea of “normal” has taken a beating over recent times. You’re right to question this. Don’t stop questioning.

A coffee meet and greet in a public place is usually the next step. If they are too far away for anything like an in-personal meet up and evaluation, I would drop it fast.

Short interactions, complete stranger, serious relationship. This smells like a scam to me. Proceed if you will but with due caution. Call me cynical but I expect he will ask you for money quite soon. Don’t give it to him.

If it walks like a fish, and talks like a fish, and especially smells like a fish, it’s most probably a fish.

No, it’s not okay.

Does ‘get in a relationship’ mean have sex?

I would recommend agreeing that when you meet in person, you both acknowledge that a new relationship (an in-person one) will begin at that point, whereas until you meet someone in person, you have an Internet relationship that will naturally be limited and skewed by the lack of in-person communication.

If you’re an adult, then there’s no reason not to meet someone in person after you’ve just contacted them online, but you’ll be starting a new relationship once you meet them.

This sounds like a scam to me.
If the person asks you for money so you can get together, run.

It’s fine with me.

Nothing wrong with wanting to meet someone in real life after you have met them online. But to jump into something serious is not really a good thing. Remember that online chat is like a giant costume party. People can be anyone they want to be. I could pass myself off as a young stud millionaire instead of the middle class old curmudgeon I really am. I could tell you anything I think you want to hear.

If someone is asking you to get serious, tell them to slow down and meet them first. Listen to @janbb. She is a wise penguin.

If they want you to send Bitcoin to some obscure exchange, run.

I once received a message from someone online saying,

“You’re going to fall in love with me.”

I thought it was a prank from someone who knew me. It wasn’t. Seems it was from a woman in a state that was a 2 hr. drive away. She explained soon afterward that her determination to find a mate on a social media platform we used prompted her to embark upon an extensive examination of profiles on that site. She finally selected me as her potential mate.

We exchanged messages for weeks but I refused to talk to her on the phone (I’m an introvert) or meet her. This was shortly after my 2nd wife passed away and I became unexpectedly stricken with sciatica. Our chats helped distract me from my wife’s death and the leg pain that restricted my ability to walk.

After a few weeks she finally convinced me to call her and we gradually learned more of each other. We agreed to meet but I had no real intention of doing so since my restricted mobility made it impossible for me to defend myself if the meeting went sideways for some reason.
We might have very well met within 2 weeks had I been healthy at the time. Her interest in vaping prompted me to change my mind and take a chance after months of resistance. When she expressed a desire to quit smoking I put together a starter kit for her and agreed to meet her on Christmas eve at a licatio halfway between where we lived to present it to her.

Long-ish story short, we began dating after that. After a year and ½ of bi-weekly/monthly visits to her state for overnight stays she decided to move in with me. A year after that we married.

3 years later she passed away from cancer.

She was the love of my life.

Is it OK to meet with someone after knowing a person a short time?

Perhaps.

I would think only you and the person you intend to meet can make that decision.
