First time poster so apologies for possible dodgy acronyms etc, and also, it's long-ish so sorry again!
So, for background: My DM passed away in 2012 when I was 27, her and DF were together until the end as it were. DF got together with his girlfriend maybe 8-10 months after DM passed away, a similar time to when I got together with DP.
I like Dfs girlfriend, insofar as I don't know her well (I live over 3 hours away), but have found it hard that DM was "replaced" so quickly and never mentioned again after they got together. I have always made an effort to include the girlfriend in everything, so whenever I go home she's obviously invited out to any family meals and anything else which gets planned. I've also invited both of them to stay in the house DP and I bought together last year even though it's really hard to have her here knowing DM will never see the place I live.
Forward to recently, DP and I got engaged March 2015 and are getting married this October. I get a call from DF just before Easter to say him and his girlfriend are also going to get married, and then another call 5 days later to say it's booked for end of this July.
I have found this extremely upsetting, I am really enjoying planning my own wedding but it's fair to say there have been a lot of tears. DM and I never discussed the possibility of her not being around for my wedding, whilst she was ill leading up to her death I never really genuinely thought she would die so soon (she was only 59). As such I have no idea what she would have wanted, and always thought she would be heavily involved in my planning and so on. To have to think about DF announcing, planning and holding his own wedding all in the last 6 months leading up to my wedding I find very inconsiderate and quite hurtful. On top of which I now get asked questions about my wedding planning which I think are "information hunts" (i.e. not interested in my dress or venue, but very interested in how you find a registrar and how much that costs etc).
I am not sure whether to have a probably very emotional talk with DF about it or not, I feel (looking back) like my attempts to make all possible efforts with his girlfriend mean he doesn't realise how much I still struggle without DM being here and how much I still miss her. But aside from making him probably quite upset, I'm not sure what the benefits are... I don't want him to move his wedding (now it's going to happen I sort of want it over) and he can't change the past. At the same time it further distances me and him when we used to be so close. He has little time for me these days anyway between work and social planning, I don't want this getting any worse because I'm upset by what's happening, but I also don't want to make it worse by having some kind of showdown...
I know it's my fault for not having forced a conversation about me struggling before really, but is it worth having that conversation now? WWYD?
