I don't even mind if no-one answers. I just need to write all of this down.
My mum and dad split up in 1984, when I was 4. He was a good dad until we had a massive row when I was 15 and we didn't talk for 6 months. We have had a strained relationship since, which I thought at one point (when I had DS) was getting better.
Fast forward to now and he constantly lets me down, never calls us, never asks after his only grandchild. He excludes me from lots of things and he has left me feeling very hurt over various things over the last 2 or so years. I actually stopped contact (the little that I had) with him in May/June after he promised he would call around the day before DS's birthday to drop gifts/go out for tea and he let us down at the last minute and left DS in tears. However, he apologised and I accepted and I think that this is because we were due at the same wedding around that time so he felt he had to clear any air before then
At the wedding he said to me "Don't ever feel like we don't have time for you." then in the next breath "But ring in advance if you want to see us" :( That was June 22.
He rang me at the end of July to mention that he was having a party tonight to celebrate 40 years of the family business. He asked me and DH to go (no mention of DS, didn't even ask how he was) and he hasn't rang me since. So I haven't gone. I said to my mum earlier that I doubt he's even noticed we're not there and she said oh he will but he hasn't. No call or text to ask where I am. I could have had an accident on the way for all he knows. I am seriously wanting to cut him from my life. I've missed chinks out so it probably all slunds very petty but he has been very hurtful and a shit dad.
He hasn't rang to ask how DS is getting on at school after his first week back or anything. He is a self-absorbed shithead.
