Bro TS,
However a cure for herpes has not yet been developed. Once infected, the virus remains in the body for life ....
Nevertheless, me salute you for your honesty ...

and you are a responsible person, we can tell ...
Option 1 - I reckon you be a "NO SEX" bf to her first ... until she cannot tahan ask you ... why
When she ask ...... you can choose to tell her or break up with her ... FOR HER GOOD ...
Option 2 - since you said you felt in love .... just give her your love and see her happy without becoming her bf .... one sided giving love to the one you love could be quite comforting as well (especially come to such cases).
