Splitting incisions. When is it safe?

I do have a question about splitting I am maybe freaking out.. I had my surgery 6 weeks ago everything looks really really good. one still have a little scab where the T incision meets (I know this is commun to take longer at that place to fully heal). I just found on the internet some people had splitting incisions I am freaking out about that.. poor ladies that goes through that.. I would like to know when are you "safe" for that kind of stuff not happening?
