Hey healing-
I think I am overreacting to my situation because it is not so bad as so many others I read on here. I only dated my BPD for 6 months. We broke up a month ago and went NC 2 weeks ago on bad terms (his choice). We only had 2 good months, the rest wasn't fun for me (but of course I was addicted at that point).
Doesn't matter, you feel how you feel, and the way a borderline attaches gets its hooks in deep. It's important to feel everything all the way to get it through and out of you, so no point thinking you're overreacting.
I know in my head that NC is the best thing and I wish I could erase this person from my memory, wish we never met really. My head knows that this was a toxic relationship and wouldn't last. My head knows that we were not good for each other and we both needed to move on.
So what is wrong with me? Why do I keep wishing he'll contact me? Why am I so sad? I am still having these waves of crying throughout the day. I feel so overdramatic. The tears just come and I try to "mentally release" this person from my head.
Nothing is wrong with you, borderlines attach at the deepest level, it's survival for them but it touches us to our core. This is actually the good news because you can use the pain to dig deep and really get to know yourself, which doesn't mean there's deep seated trauma that is in need of healing or 'fixing', it just means you may see some sides of yourself you didn't know where there or you hadn't acknowledged, and seeing that can end up being the gift of the relationship.
I don't even know if I'm missing the person, maybe I'm just missing the feelings they gave me so long ago.
Good call, now you're onto something. It's common around here to have a conflict between our head and our heart, weird right? Our head knows what's right, that it be over, but our heart protests, because of 'something'. Most likely it's feelings you had with your family when you were very young, not necessarily bad, maybe warm and fuzzy, familiar, and you got them back for a while with him, and then they were taken away. Digging for that can be fruitful.
How do I get past this?
By doing what you're doing, reading, posting, go see some professional help if you need it, and most importantly take care of yourself very well and feel everything all the way. More good news is a wiser version of you will come out the other side, and you'll get not only your life back but a better version of you will live it. Take care of you!
