mil keeps disrespecting me

not sure if this is the right group to post this but i need advice

my sos mother has never liked me, i know this

shes literally told me i stole him from her 🙄

anyway we are sleeping in separate rooms because i have problems with this pregnancy, pain, insomnia, etc.

he left his phone here on my charger, it goes ding at 12:15am so curious i just glance and its from his mom

since i glanced right away i got a preview of the message, it said "whats baldy doing"

backstory * do to pcos and other health conditions i am overweight and i have lost most of my hair, but my so doesn't care he loves me

but this isn't a first, ive seen messages from her referring to me as fatty, bald, fat girl, and other hurtful things,

i have never ever disrespected her, neither to her face or behind her back

this just really hurts my feelings, and now am just crying alone, i guess he doesn't defend me since its their private conversations, and he is pretty quiet in talking back to her but it still hurts me

my parents have never disrespected him like that and he knows it, it hurts to know she still talks this way about after 2+ years

i just feel so sad, depressed and dont know what to do

sorry long post
