what should I do?

I’ve been seeing this guy for 2months and he refuses to commit to a relationship he says were boyfriend and girlfriend and he has an older son who’s 16 but not sure if he wants to be with someone who has 2 small children mine who are 4 & 8 and when I see him its when I don’t have my kids only when I do he will not see me and makes comments about my kids would probably ask too many questions to him and get on his nerves… I really like him a lot and love my kids what should I do?? Give him a chance to commit cause its still early in the relationship or what?
