Has she infected me with something dangerous?

We broke up 3 years ago and reunited a month ago. We've been friends all through. She's been having small boils that keep shifting all over her legs and sometimes groin area.

Her numerous tests has always been blood infection and low RBC. However, she started developing small, itchy rashes with an extra reddish color around her privates. At some point, she got 'hard' nodes but later disappeared.

The boils keep healing by themselves but never ending and forever shifting. Last week, I developed a small boil on my stomach, just like hers but healed after like 4 days. Yesterday, I woke up to an itchy groin and small grey rashes. Some areas are pinkish. All this time, we've been using protection.

Her on and off boils have been developing and healing for the last 2 years.

Did I make a mistake getting back with her?
