Why did I do this? (I had a perfect friendship)?

Ok I was with this guy lets say his name is Tom.We were together we me to n my-yearbook together for a while.Then we had I know bad of me...then next day he txted me saying he felt bad & saying we should be friends.So we were friends we wanted to be fwb so we were had again yesterday & then went to the mall he told me he felt bad.And yeah but I never told him something before we went out I have hpv (cervical cancer) It came into my head yesterday when I saw all the little kids at the mall (knowing that I couldn't have kids) so I told him I have it.He asked me can I catch it I said i don't know.I don't remember what they told me if it's a std or not.I hope it's not..Anyways long story short he said I don't think this is gonna go any farther.He told me we have to end this friendship n then he told me how do I know what else your lieing about? Note I didn't lie I just forgot to mention it to him.And now I feel terrible because I care for him so much & he told me leave him alone. This is hurting me so much in side.I don't know what to do please help
