witch of a MIL... long post

my SO was just trying to be extremely sweet on facebook about how much he appreciates me and loves our 4 year old little girl and our new son who is soon to be born in 8 weeks okay well I HATE my MIL she's a terrible person and she likes stealing spotlight like shes important but she talked shit about our 4 year old because she's a horrible person so we've refused to let her know gender of baby #2 or let her see any bump photos sadly he didn't even think and posted pictures and said were having a son!!! I'm so pissed off!! not really at him because he was being so sweet and didn't think about her so I didn't get mad at him I'm pissed off because the fact she's going to take the bump picture and blast facebook saying she's getting a new grandson and I'm so mad right now she acts like shes the best damn person on the planet but she's not! 28 drug charges against you doesn't make you a good person neither does the fact you robbed people and were a shitty mother to yoyr own kids she's told people the baby will live with her I just can't stand her!!!!!!!!! rant over.
