I don’t like my family?

I’m dealing it’s a lot of stuff right now and recently a family member came into town when the last time I’d seen him was when he took me to Seattle by myself and my family let me because he had a dog and I wanted to help with the dog. He met his girlfriend up there and it was a studio apartment and they had sex when I was there so I hid in the bathroom and I was scared because I had been through something sexually traumatic a year earlier on a trip. And so I went to the airport and it was the middle of the night I don’t know why I freaked out and my family said they wouldn’t help with the ticket so I spent several nights in the airport and had to get advice from an employee there. They bring him into the house a lot without warning and recently they told me I was at fault because I didn’t pay for his gas on the way up there. They never cared about this and ignored it.
