My father and I have a... minimal but strained relationship.
Divorced at 7
He cheated
Ended up marrying the woman he cheated with
Lived with her and her kids
He only rings me on birthdays and christmas.
Over the years, particularly early years he did some pretty unforgivable things. He physically abused my DSis and my DM. Things a child should never witness.
He treated his wife's family like they were his and it was quite clear that my existence was an inconvenience. A painful reminder perhaps.
I have tried to confront him but there's always an excuse.
I have had to come to accept that that is who he is. He's not a good man. He did it to his other daughters too. He doesn't do emotion and he doesn't do confrontation. I just have to accept that that is who he is. He will never change. He's 70 now and he's had plenty of opportunity to show me he could put love over his temporary discomfort.
Some days are easier than others to accept this. I have deliberately kept comms to a minimum because I can't take the heartache and the reminders. I can't keep getting my hopes up that he will step up to the mark only to be heartbroken again
I think you need to do the same. Cut comms. For your mental health and sanity. You will never change this man. He will never see you any differently - as heartbreaking as that is, it's the truth and I think you know it on some level.
Write him a letter if you must, explain how you feel and why you are cutting him out. But if he doesn't beg to be part of your life, if he doesnt jump at the chances to see you and experience life with you, then he doesn't deserve it and he doesn't deserve you.
One day he will regret that... when his girlfriend has left him, when he's older, when hes alone etc.
On the flip side, you will take this experience and use it for positive. You will most likely ensure that your little one never has a similar relationship with her father. I know I do... even if my OH and I ever split up (God forbid), I would do everything in my power to make sure they had a wonderful relationship and connection.
I wish you lots of strength OP. I don't think anyone has ever broken my heart more than my Dad. I really felt your pain reading your post and I hope you find some peace with this soon.
