i first posted this in AIBU but i think it might be better posted in here as there is more likely to be people that are in / have been in similar situations! so apologies for posting twice...i hope someone can offer some wise words.
my DD is one and has a 14 YO half sister, who is her dads (my dp's) DD from his previous marriage. dp split up with his ex 4 years ago and we have been together 3 years. I have a 4 YO old DS from a prev relationship. me and DP are engaged.
DP's DD took it v badly when they split. her mum tried to get back with DP when they first split up but he didnt want to. When he started dating me, she hit the roof and started making it difficult for DP to see their DD. and he thinks she was bad mouthing him to her as well. she even sent me abusive messages calling me, DP and DS (!!!) all the names under the sun.
When their DD found out dad had a new girlfriend, she was very upset and always refused to meet me, which was understandable and i was happy to give her time and hope that one day she would accept me.
We really fell for eachother and got serious very quickly. I got pregnant with my DD within only a year or so of being together. his DD hit the roof and told DP she no longer wanted to see him or speak to him. she and her mum also started sending him abusive texts and emails etc. however in Feb this year his DD got back in contact with DP and they started talking via MSN and now speak on MSN most nights for an hour or so, but he thinks she doesnt seem to be ready to see him, although, he has not actually ASKED her!!
She knows that she now has a baby half sister but she is never mentioned during these msn chats, by either of them, all they talk about is trivial things such as school and what she has been doing etc. all the drama's of the last couple of years have never been mentioned either.
They have been chatting most nights for about the last 4 months, so AIBU to think that DP should, by now, acknowledge the massive elephant in the room that is his daughters half sister? surely even his DD is wondering why her dad is not bringing up anything important with her.
