Is any relationship with a BPD successful? It always ends with one person being destroyed when emotions were created. All they are really good for is FWB, or using them during the HMP then leaving. They will treat you like a king for a certain amount of time, but when that stops, so do those emtions they had towards you. They'll just stick around after that till they find someone else to manipulate to save her after she dumps you, or you dump them for the constant lies, taking you for granted, disrespecting you, or the utter lack of respect for ones boundaries.
Giving them your heart will always end with you being destroying and emotionally drained. If you go in with no expectations and no emotional attachment, they can be the most fun women out there. I've only dated the one, lasted two years, could have went on longer, but things worked out the way they did. I made so many mistakes from the beginning, biggest one was falling for the isolation trap.
Spent nearly everyday with her within weeks (big mistake). Told me she loved me and gave me keys to her place within the first three weeks. Told her family I was the one she was going to marry on month 3. As a poster above said, things weren't nearly as bad till we signed a lease together.
She triangulated me right off the bat, one being her best male friend whom she worked with. She was the type who thought it was perfectly fine to have that male friend sleep over n get drunk together the one night I didn't she her cause she worked late. A 32 year old women thinks that way when in a committed loving relationship. But if I did something like that, she would have left. Could write a got darn book on my experience. It lasted about two years and in that time, I experienced the best times of my life, the worst times of my life, two abortions and now left in the worst, most depressive state I could have ever imagined on top of her giving me HPV. Towards the last 6 months she was hiding her coke and alcohol addiction from me. I'm more than sure she cheated, but never found solid proof. Her thought process was that of a child, her impulsive behavior was beyond draining. Forget about respecting ones boundaries, she gave zero phuks most of the time. Always played the victim, lied more than anyone I ever met, tried to justify those lies, manipulated, gaslit. Hell, I had proof of crap she and she still tried to deny and say it was a joke.
She bought me tons of gifts, treated me like a king, did some of the most sweet things for me, had me really believing I was the love of her by asking me to marry her 100 times. Deep down I really thought she was capable, but just needed a real strong man to call her out on her BS every single time. Most likely she would have leave anyways, as they need to control the relationship. She once yelled at me saying "you will not control me". There was one instance I remember during the last couple months that me realize this girl just isn't capable of a healthy emotional attachment nor true love. That all the crap she spewed was nothing more than lies. Let me stop here, as I can go on for hrs.
