<human>: I have some weird family dysfunction in my extended relations. This is to give a little context. 

I wanted to invite cousin 1+2 to our wedding, but not cousin 3+4. When it comes time to send save the dates, we find out cousin 2 lives with cousin 3. Dammit.

 Sooooo, I think to myself 'cousin 3 and I were very close as children! Maybe it would be OK, and they live on together, would be awkward to invite one sibling and not the other.'

So we send the mail, with both cousins I wanted, and one I really don't. Because cousin 3 is really messed up, they have issues- including stealing. 

Then, not 5 days later- I find that cousin 2 broke up with their SO and is moving across country to live with cousin 4.

I have no idea now what will happen. Another relative told me to make sure cousin3 gets **no** access to any gifts. I'm really unsure how to treat any of this. Advice, help, anything welcome!

Could you distill the essence of the text into 1-3 sentences?
<bot>: I sent STDs to unsavoury relative because they live with cool relative- cool relative moving across country. Help.
