That’s it really. First serious relationship/breakup, unhealthy relationship for a lot of the duration, but now it’s over I feel horrific.
We have 1 DC who has NC with ex (his choice.) He dropped us both because he met someone else earlier this year. I only found out that was the reason a few weeks ago.
I feel heartbroken, angry, depressed, empty, cautiously optimistic then the cycle continues. When I found out about the OW and how long it had been going on, ex gaslighted/denied and other typical narc defence mechanisms. I didn’t buy the excuses, and he chose her.
The bit which is destroying me is our lovely DD who he’s completely abandoned, emotionally and financially. Sometimes I feel like I’m making some progress and then I look at her (they look very similar) and my heart breaks a little bit that he’s decided we aren’t worth even staying in contact with.
He treated me awfully a lot of the time but even that knowledge doesn’t comfort me. He’s also very vocal about how in love he is with OW (they’re now in a very public relationship) and he’s always been completely inactive on social media before they went public. We have a lot of mutual friends, and I suspect he has been feeding one of them things to say to me - trying to spread a seed of doubt about the credibility of his love/relationship for her, probably because he wants to keep me on the back burner or as back up sex. Which does wonders for my self esteem
I know he has no good intentions towards me or DD.
I truly never felt the way I did about him, I know it sounds naive and childish. And now it’s like they are living the life I thought we had in our future - apparently DC are on the cards already.
I just want to hear if anyone else has been though horrible heartbreak - with DC involved especially because it feels like I will never have closure. I’ve tried being angry at myself to try and snap out of it - being so pathetic over someone who would treat me and DD like this - but it’s failed miserably, the pain is very deep and I’m not sure how to process it with the lack of closure. 
Sorry for the sad rant. It’s definitely one of those nights.. just want some hope that I will recover from this and the sadness and hurt won’t last.
