If you were not vaccinated then go get it.

My first girlfriend had HBV. She informed me about it and I went ahead with it, luckily I had been vaccinated. Don't fucking risk it, if she informs you about it don't do anything with her. As it is said here 'she's not yours, it's only your turn', she's simply not worth it. She will dump you for someone else, might be cheating on you, might be stupid golddigger or as it was in my case after she fell in love with me she mentioned her past CC stories. Her ex of 4 years 20+ years older cheated on her and in revenge she was sleeping with random guys(they are not together but she still drives his car lol after 1.5 years). It went all downhill from there and we broke up. Who knows what else she was doing. I heard from her cousins recently that she was abusing amphetamine and they told me not to do anything with her.

So don't be me and don't fucking risk it.
