What happened next was a mixture of good and bad things. I think we were all unsure of what to do or how to feel so we just tried to move on without really dealing with it all and that's how it felt for a while until our dad stopped seeing us as much and every time we saw him it was as if he had changed. He became a totally different guy, he was happier but he wasn't the dad we loved and knew. He moved in with his girlfriend but it was awkward for us to go to their house to see him because the woman was the mum of our friends so that caused us to see him even less.
Things in the house were starting to get better, there was less arguments,less hating each other and more understanding for a while. We got used to not having a dad and just got on with our lives but i was still self-harming. It got worse when we found out dad was getting married and that it happened without us, we never were invited or thought about. It happened just before my 18th birthday i think (not good with dates), that was one of the worst things to happen since he walked out on us.
I stopped speaking to him for about a year after that and to be honest i don't even think he cared because he didn't try to talk to me or see us after the wedding. Should've realized how bad things were because he couldn't remember any of our birthdays and sometimes didn't get us anything for Christmas. We gave him plenty of chances to be a good dad and be there for us but he didn't care, he cared more about his new wife and new family.
Got back in touch with him but it's turned out the same again and so far i havnt spoken to him since christmas almost 2 months now and i feel better because of it.
