I posted back in February to ask for some advice on improving my strained relationship with my younger sister. We haven't had one big falling out but over the years there have been a number of things that have made it difficult to get on. Most of them could have been sorted out if we had talked about them one to one, but this never happens because my family's method of dealing with conflict is to ignore it and I very rarely get to see DSis on her own anyway (this has been the case ever since she got married). I did meet up with her on our own after my previous post - lots of posters said clear the air and it helped a bit, although she spent all evening talking about herself. Anyway, since then we're back to where we started.
In a nutshell, the situation is that about 95% of keeping up the relationship rests on me and I am too busy (and getting too fed up) to do all the tiptoeing round her many issues and requirements that I used to do, in order to meet up. She suggests that we meet up in her town/at her house, which we do, but she's unwilling to travel to ours. She maybe comes once a year, despite apparently finding it straightforward to travel to DPs, who live further from her than we do. She will meet in central London but there is always a lot of argy-bargy over where, when, what and chopping and changing of arrangements.
If she were a friend rather than my sister I would drop the friendship, because she doesn't even seem to particularly enjoy my company and I constantly feel on edge around her for fear we will have an argument about something and because of all the things I can't mention (she has had a lot of career and life disappointments).
I see her at my DPs from time to time and that is okay, although that makes it even clearer that she has some issue with me as they live further from her than I do. Also, the visits are always arranged by her with DM and DH, DD and I are an afterthought. Basically, we can see them if we can make ourselves available on a particular date.
The problem at the moment is that DD (age 4) is really fond of her cousins and constantly asks when she can see them. I'm at a loss for what to say to her because obviously I don't want to say "we can't see them because I can't stand another 20-message text exchange with DSis which ends up in her cancelling or getting the hump about something anyway".
DM just shuts down any discussion of this situation but also constantly updates me on DSis's news, sends photos of them doing nice activities together, tells me what a lovely time she had babysitting the DGC while DSis and BIL went on a night away, etc (I don't begrudge any of this - DM is lovely to my DD too and sometimes helps us with childcare). DF does this a bit too although at least he had a sibling he didn't get on well with, so he gets that a bit more than DM (only child). However, I find it all upsetting partly because I don't really understand why my DSis has essentially delegated our relationship to DM and also I feel really upset to have been so marginalised in my DNieces' lives.
I feel like I'm in a total non win situation here. What should I do? I'm so fed up on DD's behalf and feel that I've let her down (I didn't have any cousins growing up) and am also fed up with DPs pretending that everything's fine while (probably, unintentionally) rubbing it in my face that they see a lot more of my nieces than I do.
Have I got any options other than pretending everything is fine? DH is so fed up with me going on about this and I can see his point!
