This is very emotional and over reactive. But you guys know how Bpd can be. Strong feelings very quickly. A little over a month ago, I started seeing this fella; about a week or so ago he asked me to be his girlfriend. I was so so happy. Through your the past  week, he kept talking about mutual friends talking about their bodies, how he found people attractive in ways that made me hurt inside, he said sexual hints towards me being able to have other partners.. not my cup of tea. About three days ago I asked him what kind of relationship this was going to be, which I should have asked before I said blindly yes to doing so. Monogamous? Open? He basically said he doesn’t see what him or I fucking another person would do and he doesn’t see real commitment as a thing until a ring is involved.. idk if I can accept the fact that I just accepted to be a side hoe... I just totally am allowing for him to find someone else, and allowing it to happen right under my nose. I’ve been crying a lot, and in a very weird head space since... I know I can’t do this because it’s already eating me up. I’m just not sure how to tell him what I’m wanting, and see if we can’t work something out, just suck it up and pretend like I’m the only one.. or just move on to someone who’s just all about me. It just hurts I had high hopes, and I thought this was going to work out well..  I haven’t told him about my Bpd yet, but I went over there last night and cried for a good chunk of time. I’m a lot more needy then he is, and  I want to see him often, he is fine with distance. Lord help me I’m a mess... what should I do?
