I'm sure she would be angry if she knew that.
×And, we had lived together before.
○We have lived together before.
Usually it is improper to write "and" to start a sentance. If you are speaking it doesn't matter, but when writing anything it is considered poor grammer, just a note for future reference.
Also say "have" instead of "had", because "had" is used more on possesion items.
Example: I had a dog when I was a child.
Even though "had" is proper to use when past sometimes it just sounds odd.
Also when writing "I am businessman" make sure to put an "a" or "an" before
Example: I am a businessman.
However there is a rule with this. You can never put an "a" in front of a vowel. You must put an "an" in front of a word that starts with a vowel, (a,i,u,e,o). So..
× I ate a animal for dinner.
○ I ate an animal for dinner.
You can use "a" if it is anyword that doesn't start with a vowel. (ex. a cat, a firetruck, a piece of pizza.)
