Rude granny am I wrong

Ok so am I wrong I haven’t talked to my granny in 6 months because she was very rude to me. So I had my baby at the time of the incident for only 3 months. So we went to visit my dad(he’s incarcerated) and as we are waiting on him to come out my brother his wife and my niece went to the vending machine so it’s just my granny and I she had the nerve to tell me my hips getting wide and need to lose weight first of all before baby I was 140 after baby at this time I was 160 so 20 lbs over which is mainly tittie meat (breastfeed) like it really hurt my feelings thn I bought to her attention that it hurt my feelings and she said “well u gained weight and you need to lose it I bet u can’t fit in your old clothes” I told her I actually can all my jeans( size 5/6) like she was inconsiderate even after I told her she was rude and hurt my feelings so I wrote my dad and told him that I give up on working in our relationship (her n I was never close was trying for my daughter sake my mom passed away so wanted her to have a granny) he told me to let go because she’s old idc she’s a woman and as a woman uk u don’t touch on weights especially after you just had a 8lb bby in you) sorry for long post so am I over reacting she’s been calling leaving messages etc I do not answer 🤷🏽‍♀️
