Family is a joke!!!!

Okay so for the last month I was worried about a baby shower and if anyone was planning one. My husband finally confronted my sister in law and said he was going to throw one with me. Her response was "oh well I was going to throw yall one" so we said okay and moved on. They made a facebook page and made us admins so we could invite people SO we invited all friends and family. She freaked and said woah the church is paying for the shower and it's just for church people! (Her church not ours) which is fine. She then said well I'll throw you a shower for the family and friends. THEN proceeded to say she was going to ask a family member that we have PURPOSELY stop talking to to throw a shower for us or ask my EX boss to throw one! I'm kinda ticked off about all this. I told her I was going to throw one for myself because she said we don't have a say  so in the church shower like who WE get to invite and all we can do is show up. OTHER FAMILIES JUST SHOWER EACH OTHER. I'm so frustrated and this is causing so much drama. ON TOP OF THAT, she's pregnant (like 6 weeks) and is already annoying me with all the baby stuff she has that I don't!!! I hope she doesn't expect a shower from me. I'll just ask for a church to throw her one. Anyone else having this much trouble???
