Hi.
To cut a long story short..
My partner and I have been together 3 and a half years and have 2 babies. He proposed this Christmas time which I was very happy about and immediately started thinking about wedding planning.
My partner was previously married to someone else and has 2 other children (13 and 15) with his ex partner. The complication is that his brother (and supposed best friend in one) is married to his ex's twin! They broke up apparently as she cheated with someone else from the group of people we would mix with In the distant past/ because of alcoholism and mental health problems? To be honest I've never really been able to pin down a reason for why. It seems to have been her choice to break up despite all this and I remember the twin telling me she 'kicked' him out one day to live at his Mum's and that was that really. I feel aware very that he wasn't the one whose wanted this to end but we are happy together now and he doesn't seem interested in her anymore.
In the past me and the twin have got on okay however my partner's brother and her have left him out of multiple things they have planned and this has become increasingly moreso the past few years. My partner claims he had to chase them down to be invited to things before I was in the picture however I've always been unsure as to why they leave him out of friend/ family plans and never think to invite him? I can see that he's been hurt by this before and that makes me feel terrible. I sometimes wonder if it is anything to do with me? They were all together since early 2000s and I've stopped going to Sunday dinners recently at his parents' house as I realised I wasn't enjoying it because every now and again people will ask how his ex's job is going to his sister or the twin will bring up distant memories in front of me and my partner leaving me feeling awkward and confused. All in all I've felt I'll never really be sat comfortably in this very insular family and that I really don't fit in and why spend my weekends (some of my only respite time between my difficult job and babies) feeling awkward and cringing.
I would like my wedding to be just a good day with people I want to have there. It is my wedding after all and why would I bend over and put myself out bloating for heads and having people looming in the background who make me feel awkward. The twins are identical and when is ay they are they really are.. if you had first me them it would be difficult to tell them apart down to the content of their conversation, their lifestyles, clothes choices etc.. I would really like to at least not invite the twin sister however my partner says he would like his brother there and I'm not sure how to have one without the other. They had 2 kids also similar age to my partner's and they'd have to be invited too. My partner feels his Mum would be upset if he didn't invite everyone.
Has anyone any ideas or feelings about this I just would really like some objective opinion?
