If you have a healthy relationship with your mom, it could be that she just wants to connect- it's a normal thing in relationships, especially if you don't see each other all the time or aren't very involved in each others' lives.

My parents live on the opposite side of the country from me, so i typically only get to see them a few times a year. To keep in touch, I talk to both my parents on the phone pretty frequently.

My dad and I talk probably more days than we don't. We chat about work, hobbies, and sometimes the news. He and I are both engineers and we're on a similar wavelength, so we get pretty deep into work and I go to him for career advice.

I talk to my mom maybe once or twice a week and usually it's about more surface-level stuff: the dog, family updates, my relationship, and what we've been up to lately.
