I'll try and keep this as short as possible... I wrote a post about this situation the other day.
So I've always had 2 close friends, friend 1 and friend 2. Friend 1 had a serious DP who she lived with, unmarried, no children, and he was always close to me and friend 2 as well.
Friend 1 and friend 2 have both been really good friends - but friend 2 has been there an unimaginable amount for me but I've got a lot closer with friend 1.
Now, mid last year, friend 1's DP left her out of the blue for friend 2. She is still angry 7 months later, and I inevitably chose sides and due to the weight of the situation, haven't spoke to friend 2 since.
I got in contact with friend 2 last week as I felt I owed it to her after how much and how selflessly she's been there for me for 10+ years. I haven't told friend 1 and she'd be angry if she knew I'd be in touch.
Now, I've been going through a really hard time lately and friend 1 has hyped me up about a weekend out (rare for me) this weekend. She's now started making a few excuses about why she might not be able to come. She knows how much I needed it and she's still being a bit flaky regarding plans.
Would it be really bad to contact friend 2 to come and have a night with me to cheer me up if friend 1 cancels? Friend 1 would be livid if she knew I'd gone out with her but she also knows how much I need a night to let my hair down and is still making excuses.
Hope this makes sense!! It was a bit confusing to write so well done if you made it to the end!
