Society says in not in love

I have been with my boyfriend for 2 1/2 years at the beginning we were like any new couple we were jittery and nervous around each other and our hearts raced so fast but now when I’m with him my heart doesn’t race my heart just feels calm and at home with him I don’t get jittery or nervous anymore bc I am so comfortable with him but people keep telling me that I must not love him bc if I did I would get that jittery nervous feeling...... is this true (I have severe anxiety so this may be an obvious question but to calm my nerves I need to hear it from other people)
