Less than average familys?

Hey are there any family's out there like ours? I'm 19 my wife is 32 (PLease no trash about it) and there's still a baby's father pokeing his head in. Our little family is about to add a baby boy(from me) I was with the baby's dad shortly before I met my wife who is the love of my life and then we discovered we were pregnant and I tryed with the baby's dad and she understood they I wanted not to have dramma with the baby....but he refused to work and I had to support him for a long time and finnaly I told my wife I was ready...I'd been ready a long time we are now 5 months pregnant. ..and I am really in need of a freind who's family may be different.....I see all t hease normal family's and I feel like iv failed my baby some how.....even tho I know I havent. And it doesn't help much that iv had to serve a restraing order on my mom( By my therapist recomendation.she's not rlly there any way). But this is my first one......so I feel alone and surrounded by people at the same time..anyone out there?
