DB, I have perhaps been hard on you at times. But, I definitely come from a place of caring. I will echo OR here that just talk man. I have had my heart broken numerous times through the years. Hell if it helps you my high school sweetheart crushed me, my first love. That breakup was brutal. Nothing disordered about it though, we were just young and for how deep our relationship was...probably in over our heads, but I wouldn't change anything because it is a part of what allowed me to become who I am today. And hey honestly it took me a couple years to really get past it. I loved that girl and truth is I will until we leave this earth. However, I moved on and realized that was a huge stepping stone for me. I am hoping for you that you will get to that place to. For reference I dated that girl from a Freshmen through to my Senior year. So it was a big deal.
I can see your feelings are quite real and deep for this girl. However, in due time while the feelings could remain I do think you will come to the realization that you can love someone but that you do not have to be with them and that you can love and care about them from afar. It takes time but you will get there.
No more though because I have been in your shoes and I know some of these words of wisdom may actually just irritate so I am going to leave it mellow for now. What I want from you...just continue to share. Feel free to ask generalized questions to. Don't just focus on everything related to BPD. This is key. This is the detaching board so you have more freedom here.
Keep your head up! We are here for you and have your back!
