Have namechanged for this and will also be slightly vague for obvious reasons.
I have an awful dilemma on my hands and I'm extremely upset and worried about the whole thing. My DH is currently 'away' and is home on RnR for 1 week in mid April. His tour was unexpected and happened with fairly short notice as he was replacing someone else. We accepted that these things happen though and battled on.
I have had a fairly awful time since he left with a sudden and unexpected health scare (all ok now!) and a household emergency which was very stressful. So I can't wait to see him and we need some time together.
Some months back, before we even knew DH was going away, I agreed to be a bridesmaid for a friend. The wedding is, you've guessed it, mid-April. DH is due back the Thursday before the wedding, however it is a very high maintenance wedding and I am expected to be there on the Thursday before and have various tasks allotted to me on the Thursday night, Friday day and evening before we even get to the wedding.
All this would mean I couldn't see DH until very late Friday night at the earliest. He is coming to wedding but friend has already joked (
) that we will hardly see each other that day and she has put us on different tables and although I've asked, doesn't want to change the seating plan. 
I am also expected to be 'on duty' all day Sunday hosting relatives from overseas as there is a big lunch at her parent's house and she asked me to help transfer wedding gifts back to their home on the Monday as they will be on honeymoon. So basically 5 days of wedding duties and then DH leaves on the following Thursday so we would only have 2 days together.
There are 2 other bridesmaids but I am unofficially chief bridesmaid. I want to pull out as I just can't face this and she is showing no signs of wanting to understand my situation. I would still be there for her - I just want a scaled down role.
Help, what would you all advise?
