Twitter help please?

[Alem]

Ok, so I was looking through my ex-friends twitter account and i acceindently followed her. I didn't realize until 5 min. later that i followed her, but she barely goes on her twitter from what i can see. I know when new people unfollow me it automatically unfollows the person but i can see their name on my connect section of my twitter for a while and it goes away after a while . If i changed my name, picture, username and deactivated my account will the person see i followed them on their connect and know who i am. I know this dosent sound like a big deal but it is to me. Thx for the help
