Friend of mine not massively close but she is lovely and has had a rough time recently. I probably see her afew times a year. About 6 months ago she told me she was having a party for her 40th (this month). However since then she hasn't had a great time and nothing was mentioned. I didn't want to bring it up and we had only spoke 2/3 times in the 6 months.
A couple of weeks ago I booked a short break as it's school holidays I think the dates had slipped my mind and tbh I assumed the party just wasn't happening. Which retroactively is abit stupid.
Anyway she rang me yesterday out of the blue to confirm I would still be coming. I was completely out on the spot. Instead of being honest I came out with nonsense about childcare issues completely forgetting some of her friends are friends with my sister. I now keep thinking it only takes a couple of conversations to find out I lied. She has also taken me abit back as instead of just accepting my no she has come up with loads of suggestions can I not use a local baby sitter service etc. I said i would look into it and get back to her. So I feel really bad now.
I know I'm an idiot I just didn't want to hurt her feelings. Would you tell her the truth and apologise for lying or do you think this will make it even worse?
