OH wow I forgot I posted this.
We split up. I fought with him for almost 2 weeks about getting therapy but he still refused and was putting no effort into making it better even when I explained how hurt I was, so we separated. Good riddance really as he's turned into even more of an ass-wipe since we split
Has only seen his kids a handful of times because he's 'too busy'. It's DD's birthday today and he's not called or even messaged yet. I messaged him to ask if he had a gift or anything, but no reply.
Was difficult at first but he's made the split easier by acting the way he has. I've began to realise I didn't know him at all to begin with.
