should i be worried?

[Dino]

both of my cousins are going out

one of them is on my dad side of the family and other is on mum side of the family

they are not blood related ,

main to question is , should i be worried it feels weird

second it are they cousins , i heard they are not cousins

[JoeyN]

Nothing wrong at all. They are not related, you only feel weird because they are both your relatives.

[JackBurton]

if they arent related by blood, no. there is no problem with that.
