Do you get insecure when your partner checks out someone else , or makes comments about someone else in front of you?

We all know it’s disrespectful to do , but people still do it for whatever reason. Whether they are seeking validation , or they like receiving attention from the opposite sex or they like checking out someone they find attractive, basically someone that caught their eye and making comments when they see someone attractive in front of you. Do you get upset and insecure over it or do you just ignore it and think whatever? Or do you assume your partner is up to no good , because if they can do that in front of you , what do you think they do behind your back? Would you end your relationship with them or assume your relationship is coming to an end? Especially if you don’t do that in front of them?
