<human>: Give me the gist of the text in a nutshell

My girlfriend and I have been together 8 months. We have gotten along great and things have gone real well so far. When we first were friends i told her i had 33 sexual partners in my life, which was a lie and i actually have had 3. Its a complicated story as to why i lied about that. I wanted to tell her for awhile that it was actually only 3 but didnt want her to think i was a liar.

Last week we had a scare. I had a false positive for HIV and we were both an emotional mess because we didnt find out it was false for a few days. When i had first told her, i told her my secret because it seemed so unlikely because of only having 3 partners and never having unprotected sex. 

We are both ok now health wise, but shes upset that i had lied to her about how many people i had been with. She says in a way shes glad because she respects me more, but she says she lost a bit of trust in me. How do i gain it back?
