So I have been with my fiancé for 2 years and 8months now. In February I found out he has sex with another girl...so I had sex with another guy to show him how it really feels...problem is in April I got pregnant. (I didn't stop talking to the other guy until the very end of april) should I tell the other guy that I'm pregnant or just leave it as is since my fiancé LOVES our little family already? ?
