Welcome and hello

It's tough to go from being so close to suddenly cast out.
I feel needy.
This is kryptonite for many relationships, probably more so for BPD relationships.
As hard as it is, she feels lied to and it matters to her. A lot of BPD sufferers cannot trust other people and even this small lie confirms for her what she already brought to the relationship.
Can you give her some space and let her work her way through this? She felt you were different and special, and may need to get over her hurt.
It's often a good idea, if you are doing all the reaching out, to back away until she makes a move. Let her know, "Hey, just want to say hi and let you know I'm here for you anytime you want to talk or get together."
Light and airy, no big drama bomb filled with emotion.
Then work on being the awesome guy she first met, not needy. Confident and attractive

That's who she will be hoping to meet when/if she reaches out.
