I am in a newer relationship (6 months) that was amazing for the first 2 months then all my BPD issues started causing issues.  One of my huge relationship hurdles is Exes.   I obsess over them - the ex in this case has a really cool job in Hollywood so automatically I think she is better.  She also has a ton of friends and is one of those super likeable people.  Sometimes something small like a mention from him like 'Oh I loved visiting Yosemite' triggers me in such a huge way because I think of him being there with is ex.   I have always had this issue in relationships and when I mention it to people they never seem to understand .. like they are 'they are an ex for a reason'... so thinking this might be common in BPD?  anyone else experience this?
