また会いたいって英語でなんて言うの？

I look forward to seeing you again. Would you be interested in a second date? Would you be interested in meeting again? Let's do this again sometime. I had a great time. Would you like to do this again sometime?

"I can't wait to see you again." If this person is a good friend/ significant other you don't have to say, "I would like" because you are probably going to see a friend or significant other again. To show excitement you can say, "I can't wait to see you again"

IF you really want to do something then you can say 'I would love to' if you are really looking forward to something then you would say 'I can't wait to' A simple term is 'let's meet up again!'

To a very good friend or a significant other, you want to say something like "I want to meet/see you again". it depends rather on what you want and how close your relationship is. It seems a silly thing to say this to a close friend or significant other. Of course you want to see such people again! Better just to plan to meet at a specific time and place somewhere.

"We should meet again soon!" This is something you could say to a friend, but that could also be said to a business partner. "I cannot wait to see you again!" This shows excitement at the idea of seeing your friend, significate other, etc. again. It is something you are eager to do. You could also say, "Let's meet again when we can!" Here you are suggesting that you and your friend plan a time to meet in the future.

When can I see you again? Can we get together again soon? I want to see you again soon. OK? If you ask the question like these then you can get an immediate date to get together again. Otherwise you can say it like this: Will I get to see you again? I hope we can get together again soon. I would love to see you again soon. I look forward to seeing you again soon.

When we are with friends or even a business meeting, we 'arrange' to meet someone. This is the same as plan or agree to meet. If you are 'looking forward' to something it means that you are excited and possibly planning when you will see your friend again.
