LMo, I have to agree with Pat on this one.

As hard as it is, you need to set boundaries with them. If you let them steamroller you on the little things, they're going to do it with the bigger things too. You don't deserve that, and I know you know it.

Yes, they're the only parents you've had for the last 20+ years, but just because they're your parents doesn't mean you have to like everything they do. If you're the black sheep now, and always have been, do you think your elderly parents are going to be changing that opinion any time soon?

I'm thinking you need to accept your black sheepiness and stand up for yourself. I also like the suggestion that they stay with your stepbrothers. It's unfair that they're just using your house as a hotel and dump you by the wayside every opportunity they get. What makes your house so much more appealing that they stay with you when it's obvious they'd rather be somewhere else? They blow you off, they don't like Shane, they stress you both out. I don't see why you'd perpetuate that situation other than the familiar, no matter how uncomfortable, is easier than trying something new, especially if others won't approve. They aren't taking your feelings into consideration, do they really deserve it in return?
