Direct and sound advice is hard to give, since the particulars are unknown as to what makes your family/friends untrustworthy. Without such details, it is hard to know what to say.
In regards to your family and friends, is the reason you don't trust them because each person has a horrible fault that is cause for great concern? (ex., drinking, low morals, poor discipline, etc.), or do you not trust them to raise your kids just because they're not perfect?
I only ask because, you have made the statement that you don't have ANY friends, OR family you trust to care for your kids, but you don't want the State to choose, in case they put your kids with strangers and/or separate them.
Since you don't want the State to choose, you HAVE to; even if there is no 'perfect' couple that you know.
I have six siblings, and my parents, in town. My husband's family lives just three hours away. When thinking about who to choose as a guardian for my son should something happen to both me and my husband, I get really, really picky. I can think of a dozen faults for each… and… every… person on the list, and I become dissatisfied and decide that none of them will do. "He's too careless; I don't think he'd teach my son the value of action/consequence." "She is always too petty." "He is so disorganized and hobby-centered, my son would never learn the value of hard work!" "Those two rebel all the time, and party with some questionable characters. Their morals aren't the same as mine." "He tends to be judging. My son will grow up thinking he can't do anything right." "She never knows what she wants to do; she's not ready for that responsibility." "They are so lackluster, switching between hard opinion and wishy washy; how would our son ever know what to do?" "He hardly ever admits if he is wrong; accountability?" "She is so opinionated, and always expects everyone to listen and follow her opinion, and gets angry when they don't! Will our son end up feeling small, or will he grow up as a control/power freak?"
I could go on.
The funny thing is, if anyone were to just ask me if I thought they were good people and would make good parents/husbands/wives, I would say YES in a heartbeat, and mean it. Because they ARE good people. Some of them are married and have kids, and do a GREAT job. Others are single still. The faults I have mentioned are no different that the faults many of us have; in my mind, I blow them up into insurmountable flaws. So I have to remind myself that no one is going to parent him the same as us; but who will parent him well? Who is the closest to what we want for our son? We decided we wanted to choose within family, because we believe family should stay with family, no matter what.
However, some people do not have the kind of family they can trust like that, but have friends they do. In that case, they go with a friend who they know will raise their child/children well. Personal circumstances are always different.
You have gotten a lot of really good advice already, so I wasn't sure if I should post or not. I hope my little contribution has helped. If not, I hope my prayer does. :-) Decisions like this are never easy!
God bless!
