Recently, my now-ex-partner and I fell madly in love (idealization) long distance, with a visit in the middle of our time together going amazing and being filled with love and passion and intensity.  Since about Christmas, they began to have more and more negative episodes, painting me black or attacking the relationship/me then apologising desperately with declarations of love shortly afterwards.  This all led up to one majorly bad episode following which they went quiet and cold towards me, eventually saying they can't do LDR with me anymore.  I'm obviously devastated.

However, they did say they were still open to meeting again, when we can actually see each other in person, in a couple of months, which we'd more or less arranged, and if we could do so with no pressure they agreed it'd be a lot of fun.  I'm currently mulling over whether to take them at their word and book my hotel room and get in touch later to arrange a meeting or whether to just not visit their city as planned and call it quits entirely...  I don't want to impose and bring further pain to them, and I don't want to hurt myself if they are just being nice in saying they'd like to see me again.

So...  I guess advice would be good.  If a BPD person ends a relationship citing being in a terrible place emotionally but says they're happy to meet again in the future when we can in person, can I take that as the truth and go with it?  And even if it is, is it more likely to go very wrong than very right?
