I haven't proposed at all to this women & she has herpes treatable yes but there forever. ?

I planned to marry her then, she tells me she had contracted herpes sumtime before or after January last yr. Sexually & had a baby who's life I been involved in since he was 3 mos. Old & didnt tell me til recently. We even had unprotected sex when she already knew she had the STD. Which has me upset but I'm in pickle cause I love but dnt think I could spend my life being careful not to catch it & be with her the rest of my life. Answers pls.!
