I said no pictures!

Should I have a right to be mad because what she calls it is overreacting!? So I have facebook and yes everyone knew I was pregnant I posted 2 pictures of me with my belly 1. Because it was my oldest birthday and we went on vacation to florida to disney & 2. It was my 6 year anniversery with mt husband. My sister is so fucking toxic i hate her. Its a very long story but lets start with shes jealous of my life because her baby dad left her when he found out she was pregnant and mine stood around and we moved in a condo and he works a great job she stood in my parents till she was 27 smh im 22. Moved out when i was 18. And everyday shell make horrible comments about him and have people trying fighting him for no reason she was so jealous that she one time tried being his friend and was talling about how she hasnt had sex in so long and was trying to make moves on him! Anyways we waited 4 years to get pregnant she was pissed told me to let mher adopt it. I gave birth march 10th and we told her she cpuldnt come because her disrespectful mouth and nobody is going to disrespect my husband and do that in front of my children. I wantrd nothing to do with her every again. But I decided when my son was 4 weeks she can see him when she learns to grow up. So we met up and she started sbapping photos i asked her not to post them shr said she wont. 10 minutes later she said i posted them and idgaf what you say or how you feel. Omg was i pissed i stayed calm so i dont yell in front of my newborn who also was born with epilepsy and is on meds i wanted privacy and she disrespected me. She then went on after i said she can no longer see him again she said im bipolar i need help. I blocked her number but i just cant beleive she would do that to me am i wrong for getting pissed. Im thinking of deleting her on fb as well
