talk behind your back?
if people talk behind your back that is a shame on them, not you. If they are any kind of stand up people, if they had concerns about you for any reason, they should come talk to you about them like concerned adults and offer help if needed to help what they perceive to be any issues. Otherwise they are just gossiping fools who should keep their mouths shut.
Talking behind one's back is the stuff of cowards, and their shameful act should i no way reflect on you. I know being a single dad is not easy, having been one myself, but for people to talk behind your back is nothing but hurtful, and it is not HELPFUL in any way...so pull your head up, and be as proud as you can be and just go along and try to be the best father you can possibly be.
You are the one who ultimately has to look at yourself in the mirror and be able to say to yourself that you have put the best interests of the children over everything else in life. You need to be able to honestly say that to yourself (and mean it) or if you can't... then maybe some soul searching is needed, and some corrections needed.
Being a single dad is really tough, especially since men lack the motherly instincts of the woman, which can, to some on the outside make it look like you're not doing the best job possible... but ask yourself if you really are doing EVERYTHING you can to be the best parent o your kids. Ask yourself and be honest Look into every aspect of your parenting...the real answer usually lies from within your heart. You'll know...
As for the talk... let them. Or if you know for sure it is going on, ask them to rather speak up to your face and offer what they perceive to be solutions rather than inflaming things and talking behind your back which is nothing but hurtful.
