Unsupportive friend

Hello all,

I am a mom of a preschooler and I decided to get back to school and finish my bachelors.

I have some friends that are upset with me for not being there for them.

I’m not asking for help /support from them, just to understand that I am extremely busy as a mom, wife and now school. I always tell them that I can text /talk on the phone. (They don’t ask to visit me or ask anything about school)

I am paying for my classes. I’m taking online classes and I’m overwhelmed with work, school and everything else.

Am I being fair by telling them I don’t have time to hang out?

I’m a blunt person and have said it as nice as possible multiple times.
