The problem isn ' t the BPD mother it ' s Met her just about 6 months ago . Things moved very quickly . She described all of the past men who have abandoned her and made me feel special for being different . ALARM BELLS She meets them , is very enthusiastic about them , compliments them and makes them homemade cards , then begins sharing very personal stories with them , eventually escalating to venting and crying to them , they start to feel uneasy and back away , she starts venting about them to me , she makes them more homemade cards , they don ' t react gratefully enough , she sends a nasty text to them , they react back angrily or ignore her , she sends a sweet reply complimenting them , they don ' t reply anymore , she freaks out and blocks their number and vents more to me . This isn ' t FLEAS or PTSD , this is a very serious and well known pattern of behavior . No one here can diagnose but I wouldn ' t bet on her not being BPD . Not only that , you seem to be casual about these behaviors because they don ' t affect you yet that you realize . Her childlike , wounded and innocent affect doesn ' t make these behaviors okay . For example those cards aren ' t gestures of kindness , they ' re manipulative tools for intimacy with others and she punishes them for it . These are very serious warning signs .
