Friend likely to cancel on me

[Rosegoldlilly]

I have a big event in a couple of weeks. My Dsis went with me last year I would have asked her to go this year but she was pregnant at the time and feeling very tired/sick. (she isn't anymore due to a miscarriage). So I asked this friend. However she can be very flaky but I had no one else to ask as I have no DP and don't have any other close enough friends to take. We were suppose to be looking for a dress for her today but she cancelled on me this morning. She says she will come but I don't think she will. I don't want to turn up alone and everyone else be there with their husbands/partners. So Wwyd? I want my Dsis to come along and she said she wants to but obviously what would I say to my friend because there is such a high chance she won't go.

Bump

Just tell her you've asked your sister as you don't want to be let down

Just ask her if she really wants to come, and say she doesn't have to if she doesn't want to as your sister will accompany you.

I would just say your sis is having a hard time at the moment and you really want to take her sorry. Don't go into any details that should suffice! Definitely take your sister

Yea I did think about asking her if she did want to come but I have a feeling she will just say yes. She's that type of person that lets you down the very last minute. So I don't know what to do if she says yes
