Meredith would not have those trust issues if Derek did not lie to her about Addison and dump her to get back with her and i am not gonna mention rose she means nothing.

I think Derek´s biggest mistakes are lying or trying to move on...but Meredith has a lot of issues from her past, and that kind of thing is really hard to change!!

i totally agree with dermer4ever

Having a wife? Epic fail.

Mer!
but i think that doesn't matter anymore cause now they're finally happy together :)

Meredith is a very complicated person. She is always having trust issues and thinking that everybody is going to leave her. But I think she's better now and I hope that she makes Derek very happy :D

meredith was happy and shiny with her relationships before addison showeed up derek caused most of her current issues so i blame him

I really blame Derek for the most trust issues...sure she was "damaged" before..because of her crappy childhood but she was kind of happy with Derek at the beginning and than one night there is this woman...his wife...and suddenly she realizes that everything she has been living with him was a big fat lie...come on..put yourself in her shoes..isn´t it humiliating as hell???!!! I really admire her for forgiving Derek for that because that lying about his wife was really low! As much as I love him...he isn´t and doesnt act always so McDreamy-like ;)

Uhhh, yeah LONG comments LOL! :D

I agree with you Greysaholic.

i think its her becoz, when she finally got him again, she wasnt there for him, and rose was allowed, becoz they werent technically together, but she should have fought harder, but now they seem like they are doing awesome :)

he kinda screwed her over after the Addison thing. She was ready but then he had to go & be married ! Dumb hot McDreamy Derek !

both in there own way derek of not telling mer about addie and the whole rose thing, and then choosing addie and not meredith but meredith and her trust issues she had a rough childhood and its tough for her to trust people i can understand y, but now there working out there problems and they are finally happy and that makes me happy

Derek messed up, Meredith is just messed up.
