You have more problems than can be answered in a technical discussion about
computers.

1) There are network sniffer programs that can do this. Whoever is using the
program would have to be able to decode TCP/IP communications and spend a
lot of time doing this. It would be much easier to surreptitiously install a
keylogger or something similar on your computer.

2) Ask her.
