My boyfriend and I received my engagement ring in the mail on Nov. 25, the day before Thanksgiving. The plan was that he would tell my grandparents and mother on Thanksgiving day, then propose on my birthday (Nov. 29). Later that Wednesday evening, my grandma fell, sustained a significant head injury, and went into a coma. My grandmother was my mother more than a grandmother - she raised me for more than half my life and I talked/face timed her and my grandfather every week. She died on Friday morning, Nov. 27, two days before my birthday. 

My boyfriend and I have been together for almost six years (come our anniversary in February). Needless to say, the last two weeks have been a whirlwind - she died in Missouri, we live in Illinois, funeral was in Wisconsin. A lot of traveling happened, a lot of grieving, a lot of celebrating of her life. I stayed by her bedside the whole time she was in the hospital with my family, and was with her in her very last moments. She was one of the great loves of my life and I admired her more than anything. I am living through my greatest fear of loss, my hardest and most difficult goodbye.

While I love her very much and while I am still grieving, I also want to move forward with my engagement that was in motion before she passed. I told her about it when I was sitting with her and my mom & aunts, and my family is really, really happy for us. 

I am asking if anyone has been in this situation and how long you postponed your engagement, if at all? Or how long would an appropriate time frame be to pass before we go ahead with our engagement? I want to tell my grandpa when he has family visiting him and isn't alone because I want him to be able to be excited while surrounded by family rather than being alone. He is trying to live alone for a year before deciding if he needs to move closer to family or which state he should relocate to.
<bot>: Engagement ring was received and proposal date was set for 11/29, grandmother passed away 11/27. How long to postpone engagement in respect of her death and family mourning?
