BF mom commenting on pregnacy weight gain - UPDATE

I posted something about this last month in January about how my boyfriend of 4 years, his mom has commented about my pregnancy weight gain 3 times since being pregnant.

Well, my boyfriend finally said something to her about it, telling her it hurts my feelings— VIA TEXT.

She replied back to him telling him to tell me that she is sorry and won’t happen again.

That’s fine, but I still feel like she should have called or TEXTED me personally and told me that?.. am I wrong?.. I haven’t spoken to her since it happened mid January.
