We fell in love at work. She adores me! And I adore her! She Told me about her having BPD so I took it upon myself to study and become more patient with her. 
Don't get me wrong,  sometimes it gets confusing...
Last night I felt like she needed some extra reassurance so, admittedly I was putting myself in a vulnerable scenario. I'm still trying to read her body language,  and little things she  says that will warn me whenever she's starting to become manic. So I became clingy... she reciprocated the affection as we cuddled on the couch watching movies. 
But I still felt like my affection wasn't wanted... everytime I kissed her,  or reminded her that I love her, or tried anything romantic she just replied with "no"

It hurts my feelings whenever she says that.  But I have to understand her boundaries.  

We talked a little about it in bed,  which led to me being emotional thus making her sad.  She never wants to see me sad or be the cause of my sadness and reverse.  I told her that with her past, our love language is so different and it's going to take some time to learn eachother. I'll do anything for her, she literally is my world..

Any tips for the SO without BPD to be more supportive and understanding? 

Thank you!!
