-- Note: It's important to differentiate between Borderline and Bipolar. They are NOT the same thing, despite having the same acronym. I thought they were prior to becoming somewhat obsessed with researching it in order to understand my most recent relationship.

Just finished a relationship with a BPD girl, having previously not known anything about it. Based on my personal experiences, I'm starting to think that BPD is actually quite common among Americans (both men and women). BPD men typically remove themselves from the dating pool unless they are exceptionally desirable, but BPD women get a pass for their behavior and can simply handwave away symptoms and behavior with "I can't help it, I'm a girl".

There are two BPD subreddits -- one is a safespace hugbox for BPD individuals, and the other one is both a support group and a venue of honest discussion.

BPD people are seriously scary. They have the potential to completely ruin your life. If you're at a low point or you don't have much (or any) experience with relationships (this admittedly applis to me), you'll likely be unable to resist the initial advances unless you're familiar with BPD. Whenever you hear about "abusive relationships" or someone who is "clingy", it typically involves a partner with BPD who alternates between intense, overpowering love and detest.

The most important thing to understand is that people with BPD are fucked up, and that people who engage with them are victims of emotional and mental abuse. As a good and decent person, you will feel an overwhelming desire to help or fix them, especially since they have such tragic pasts. Sadly, this is completely hopeless, and you will possibly lose your sanity (and perhaps more) in the process. The best approach is to avoid contact whenever possible, since BPDs will resist any attempts at treatment. The few that don't are still hopeless, since there is no equivalent of treatment for other mental illnesses like depression, bipolar, or schizophrenia.

The lies and deceit, the gaslighting and false allegations...I think some people may get burned by an exceptionally bad relationship with a BPD and feel scarred for life, and even feel like something is wrong with you. I would definitely feel this way if I hadn't learned about it.

Also, There's a really good post on one of the subreddits explaining what it's like to have BPD, but I'm not sure if I can link directly to it...? But you can google "reddit Expecting the Unexpected: A BPD Breakup Guide"
