Am I the normal ?!!!

Everygirl get mad when she noticed her boyfriend is cheating her o texting a girl , But to me is nit a big deal cuz I always say to myself when he is in love with you and has all your photos on instagram and etc why should be nervous about this ? I have a very good relationship and sometimes I noticed he is texting a girl but I don't care . do not think that he is not important to me or I don't love hin cuz I do but Am I normal ?
