I met a guy on a Dating website and went out for a date. We kind of liked each other and he started to tell me about his life and his separation with ex wife sincerely. So I decided that I would tell him about H before we continued further on the relationship because I thought I would be hurt more if I liked him more and he rejected me. So I did tell him on a phone a night after a first date. He has gone quiet for about a day and came back to me and saying that we thought he liked me as who I was and that was a thing we should sit and talk before we decide to go intimacy. Our relationship last about 10 months and he did not get infected. I broke up with him not because of H too.
You can do it. If he knows and decide to go left or right ... At least you know from the beginning of he is the one for you or not and you will feel good. Good Luck !!!
