what will you do

Well that isnt enough proof for suspision...may be they just really dont look like you, so what thats not neccessary that they have to, may be hes just being a good uncle to ur kids and playing with them...well its good to think positive isnt it? well any ways if you suspect , then nothing works better than asking ...ask her about the truth....thats if ur evidence is strong enough....and those tests come later on.....

Me, I would have to have more evidence to suspect any wrongdoing! Do you have more instances to suspect wrongdoing? I think if you did have more evidence, then I would go all the way to the paternity tests!

I'd take them to the doctor's and get a paternity test done. Not much else you can do.
