How Do You OverCome This

I was in a 7 years relationship with this one guy and we brokeup in 2019 due to him cheating on me with multiple women and having sex with them. Didn't know any of this was happening until 7 years into our relationship and I happened to find out he gave me genital herpes after our breakup. He never told me he had this. Now it's been 5 years later and I'm happened to deal with these symptoms day by day and taking medicine everyday. I would never thought that loving 1 person can cause so much pain and hurt. I've never did anything to this person but to love him and taken our relationship serious. I trusted him with everything including my body/health. I've never cried so much. Sometimes I cry myself to sleep because now I feel like everything I've always wanted I will never have, like wanting to have kids or getting married. I feel like he took that away from me due to these herpes. I get on facebook and I see he unblocked me after 5 years of us not speaking to each other. I didn't say anything I put him in the block on facebook. Before I hit the block bottom I seen pictures of him with his new girlfriend and there kids together. Living a happy life (I still blocked him on there) the pain cut so deep to see things like that after what that person have done to you. Feel like I'm being punished while he go off and live a happy life. If any of you ladies were in my shoes. How would you handle this hurt and finding out you've herpes?.....Please Please no negative comments.
