Should I move on or keep going?

*Yesterday is the first time I met her.
*We are from Malaysia but I studying at New Zealand currently so yesterday is the first time we met each other face to face.

About 4 months ago I know this girl through Instagram and get her SPAM pretty quickly.
We didn't chat too often after we contact each other via SPAM as I'm not really into her that time but still interested in her. The way I chat with her that time is simply sharing funny and interesting stuffs to get her laugh, rarely talk about personal level topics.

And about one month ago I had confessed to her and she was very very surprised as she said too sudden and didn't know much about each other. I've told her various reasons why I fall in love with her and she said to get to know each other better first. Since then we had several great chats and from her messages which constantly consists of smileys and emojis. I was so naive that I thought I almost get her and I asked her to be my girlfriend one week later, but being told off by her with 2 very long messages. The reasons are asked her twice in such short period and she never met me face to face before. She not sure whether I'm the one for her and ended say all she need is time and communication.

After this I left her alone for awhile and she initiated some messages and pictures with me and I didn't chat much with her plus ended the topics quickly.

2 days ago I landed on Malaysia from New Zealand just to see her. She was shocked as I didn't tell her about this in order to give her surprise. However she was available for yesterday and after 5pm only. But our meetup for the first time lasted 1 hour only as she have an urgent things to attend to. Our interactions was constantly interrupted by her urgent messages from work.

My initial planned first date with her, In the end became meetup only, had left me devastated totally. I really have no idea what to do next as I will return to NZ on tomorrow.

Experts, can give some advices? Any constructive advices will be welcome and appreciated.

Too much surprise for her. You need to escalate consistently, not all at once. Surprises are for partners who know each other. I think saving this is completely up to you, and your charisma. Be polite, personable, and do not push for too much. Women want surprise, but not a crazy guy claiming a new love out of the blue--been there. Women feel, do they feel you? If she did not emote in that regard, then she did not.

^^ AND THIS... is why you need to move on. Nothing's going to happen now.

Never, ever, ever tell a girl you love her or have feelings for her. Show her instead.

You made it weird and immediately friend-zoned yourself.

Surprising her was probably not the best move either... You do not have that type of relationship with her.

Dude, this is bad.

Get over this girl and go out and meet other girls. You took a plane flight just to see her without telling her? that's straight up crazy dude.

Go out and talk to other girls and learn not to get so attached. You shouldn't be falling in love with girls over text messages. She didn't have urgent things she needed to do, she was trying to get away from you.

You came on too strong and it's because you're not coming from the right mentality. You're putting her up on a pedestal.

Never ever do this again. You were showing her your low value by chasing her via traveling to your home country. You were telling her indirectly that she has higher value than you. Women are looking for a man who's had a higher value than her.
