Okay so my BIL is 19, we'll call him C.

He is totally entitled and gets away with everything.

He asked my MILs for money everyday, and they always give in. Tonight C and my MILs got into a fight about him cleaning his room since the house is getting appraised tom.

So C freaked out & wanted to leave the house and go get cigarettes with his 2 friends who have been over at our house for 2 weeks now, eating all the food, making messes everywhere.

So C asked my MIL for her credit card so he could leave & get cigs. & she just hands it over, no questions asked.

But then when C leaves my MIL complains to me and my fiance about how C always asks for money and shes sick of it. But still gives him money for everything, they pay for his car (which hes crashed 3 times with minors in it), he brought a puppy home and doesnt take care of it so we do.

My MILs constantly give C money for every little thing. And then asks my fiance and I for money. We pay rent here, we pay for our own food and for our puppy. And we are paying for our whole wedding ourselves. We dont have any spare change to give you know?

C just takes advantage of everyone around here.

The reason I'm ranting is because my fiance doesnt want C (his little brother) at our wedding. Because C misbehaves at every moment, starts fights for no reason. C has ADHD & aspergers (a form of autism) he is totally capable of having a job, saving money, driving cars ect.

But now that hes 19 he doesnt want to take his meds (they keep him super chill and calm)

So my question is, do I talk my fiance into let C come to the wedding, or do I just not say anything?

My fiance will only let C come to the wedding if he takes his meds. (My family is coming a few days before the wedding and my fiance wants everything to go good because my family and C have never met before)
