@southwest I guess the only one who knows what she meant is her. But even if she meant how she interpreted you sitting on the couch meant x,y +z, based on her association to her ex and what they did and why and how things unfolded, without talking about it between you no one could understand what was wanted. It's ok to say what do you need from me, but she didn't elaborate and maybe didn't know herself what she needed, and you can't mind read. Maybe a better question first might have been, "Help me understand more?". Sounds like she forgot the first biggest thing she needed and she had was the fact you weren't her ex. It's hard for anyone else to know how someone feels if they don't say, or need more info to understand.
But that's the thing about communication, you need to have the message but also know it's received and valued or respected, and then explore it together to go forward. And in a relationship care enough to think of the well-being for both of you. And both take some initiative or risk. Sounds like far as communication goes the plane never landed. But mybe she needed reassurance or something else? She didn't really say how she felt, and I'm not sure you did. But also needed would be to own her own part. I am sorry it worked out as it did.
ETA (and I'm sorry I missed a post and made a booboo with the quote, but you said):
"I think what they wanted was someone that would always side with them and never show that they were upset. If I set a boundary say something like please send me a "I'm okay but I need space text." When they would cut communication for a week or more without warning I was told I'm not being consistent."
Idk know what she was thinking of course, but my understanding is your boundary is your response if it's crossed, what you need, such as ~"I would appreciate if you send me a text or communicate every (week/ day month- whatever you need, not BS'ing) just to let me know if you need time to yourself, to let me know you're ok or to know what you need, because I worry about you and I care and don't always know what's the right thing to do. And I also need that to feel connected and to feel we are going forward with a relationship together." That's the consitency it sounded like YOU needed. Or/ and better still, if you felt it and meant it to say, Idk what you felt but maybe something like, "I love to see you/ talk to you and I miss you. Can you let me know when you need space, or how often you want to talk? Maybe (tonight/ on saturday, the end of the day, etc)?" And/or, "You seem very upset, did I hurt you, as it wasn't my intention. Can you help me understand?" But then it takes 2 people, and the good will(img) of both. JMHO. From her comment it didn't sound like space was what she wanted from you, but it wasn't clear to me what she wanted either. Maybe she was simply too stuck in equating you to her ex. It's hard to not expect the same thing if the lessons are painful enough. And you're stuck in it and don't realize you also have to be the one to fight your own mindset and fears, even with help to do so.
