Hey, guys. This is my first ever post on Reddit. 

My girlfriend (for the sake of the post I will refer to her as Ann) and I recently got back together after a six-month break due to a lot of arguing and me being on the receiving end of what I perceived to be abuse. Since the break up, Ann has been diagnosed with BPD. 

I had my suspicions whilst in the relationship and sensitively suggested that there may be something more than anxiety / depression, but there was nothing I could do to get her to talk to a doctor. Not only would it be unfair to try to make her, but I was walking on eggshells during the last few months of the relationship as it was. Being too pushy would have caused an argument.

Ann and I bumped into each other for the first time in six months at a music festival, and seeing her was overwhelming. I never stopped loving her and the only reason I left was because I needed to get my mental health back on track. The relationship was, to be frank, draining. We ended up spending a lot of time together at the festival and talking every day for a month or so afterwards.

The reason she went to the doctors was that she realised how often she made people she loved upset and suspected that I was right in thinking there was something more. 

In the 6 months that we had been apart, Ann had been working so hard. She's done a ton of research with videos, books and documentaries and I can tell you that the difference was night and day. In the month that we were talking after the music festival things were going well. So I decided to go and see her.

I was able to talk about my female friends in front of her without her acting jealous and I made a conscious effort not to tip toe around her and she was just wonderful. It was clear how much work she's putting in. So I asked her if she would like to have another go at things. Both of us are extremely happy.

I'm currently reading a book entitled The Essential Family Guide to Borderline Personality Disorder and it helps a lot. The more I know about the disorder the easier it will be to understand her and help her when she's struggling.

So I'm asking for general advice. Anything. What to do if I find myself in a 'no-win' situation; how to cope with potential rages; and so on. I love this woman with all my heart and I want to be as supportive as I can.

Thank you for taking the time to read this and I look forward to hearing from you all.
