what is the grammatically and punctuation mistake in this memo?

I and My husband were invited to dinner with Minlu and his friend. Although we only spent a few hours each time, but we enjoyed in that those times.
Minluis is a quiet, smart and polite girl. I hope to meet her again.

Thx roger same as always ,helpful so accurate.

Roger can you tell me some reference?
to I do what you do it now for me.
If you don't mind.

No, I'm working from ancient memories. I'm sure someone else will come along and suggest a reference. They can be difficult to use though, if you can't exactly define your question.

I mean what is my grammaticlly and punctuation ?

I mean what is my grammaticlly and punctuation problem?

My impression is that most of the problem is just that you are not familiar with the way English speakers actually talk. I think it would be helpful to find some English language books, and just read for a while. Come back with questions, because you will surely have many. I hope such material is available where you are located. Oh, try to find material in English that you would enjoy in your own language.
