Thank you all for your support, advice, encouragement and providing me a safe place to vent. I was able to think out my thoughts and prepare what to say without making the situation worse.
I plan on taking your wise advice to approach my hurting feelings using "I" statements. I also plan on looking into motel arrangements because graduation is just a few months away. I don't want to miss that too. I did talk to my niece, and we plan on watching the tape together in the future. Unfortunately, she is well aware of their spats.
Families are so crazy. I guess that is why we are born into them unaware because otherwise in some cases we wouldn't stay. Disappearing without a forwarding address sounds like a great idea. I guess living in another state does have its advantages.
Again, thank you all
