During a period of not dating my on and off boyfriend, i slept with someone else. not long after i found out i was pregnant and i didnt think anything of it because it was a 3 time fling and nothing more and my pregnancy was determined to be 6 weeks in and wed been together 3 weeks prior... however now that shes 7 months old she looks more and more like him. She has my other childs last name and their father has no doubt she's his. But Im starting to.... question is, how the hell do i tell him? hes moved on and is having a baby with his girlfriend. its just a suspicion but i feel guilty.
