Paternity Test needed

So about a month or so ago i was having pretty frequent sex with my favorite sneaky link. (we always use a condom but they would always bust from friction) Next month he tells me we should stop seeing each other as our relationship was only for sex. I agreed & started seeing someone else almost immediately after (i don’t need judgment i’m aware of the situation) The new guy & i were having more frequent sex and using the pullout method. come to find out i’m pregnant & the doctors estimated guess on how far along i am says that i’ve been pregnant longer than i expected. I know I need a paternity test now but am scared to tell the first sneaky link because i don’t know how he will react. I guess im asking for some tips or help on how to tell him about the baby. I already informed the other potential father but this one gives me major anxiety. Any ideas on how to tell him?? please and thank you ladies
