I’m gonna make this nice and quick. Bit pf background: My parents are divorced and my dad has started dating someone a while back. They live together and actually also have a child (who I think of as a stepsister). And the situation is that whenever I talk to my stepmom I can’t call her mom because it just feels really weird. I call her her name. I don’t know if it bothers her but I just want to know, is it okay if I don’t call her mom because it feels weird to me.
