SIL? CUZ? BRO?

Hey mummies..just letting out. Eversince the start of my pregnancy is been stressful fr me. Both my brothers gt married frst and decide to have child after house and everitin, well i totally support them in anw. I am 5mths now and till this day my SIL refuse to talk to me as i gt pregnant after few mths of marriage. I am happy even tho is hard to believe. My brothers cant care abt me cos they dnt wanna hurt their partner which i totally understand. Sometime i feel is becos me being pregant they cant talk to me. None seen my scan and none ask me hows baby and me and even none asking the gender. How can i move away frm this? I dnt wanna think abt it everyday..#advicepls I wanna get out frm this feeling blue. Any tips??
