my significant other goes on vacation every single year with their family, which I am 100% supportive of, today was my last day seeing them before they left and I cried while saying goodbye and told him i’d would miss him. my significant other then told me that me crying made him feel bad for going on vacation and leaving. 
-as someone who struggles with bpd and fears losing people is it rational for me to cry about missing him? or is this just my emotions getting the best of me?
