You've made every effort, don't take what she says too much to heart. She'll have friends & family to make a fuss of her on the day, she'll get over you not being there.
It sounds like you have put in an amazing amount of effort all things considered, we got married during COVID and we had people we would have loved to be with us on the day drop out left, right and centre due to having COVID none of whom were also pregnant, it was upsetting both for us/them but we met up afterwards and shared our treasured photos/videos and stories of the day and in all honesty that was enough. Every one is different but don't beat yourself up over it, things happen and cant be helped. The most hurtful cancellation for us was when someone who I thought was my best friend said she couldn't attend due to having a day out booked for her and the kids at a local swimming pool which could have been cancelled or rearranged x
Baby and health comes first you spent so much time and money on her wedding preps i do not understand why you would feel guilty :/
Sorry Bit yes it’s your friends wedding a big day for her this is one of your big moments and stages in your life too, it kinda works both ways. If she knows these things about yiu, she should and needs be a little more understanding- what about yiu crying and your emotional states. And all the things you have to go thru even before the COVID hit. You know you’ve done what you can. It’s sounds like you’ve done more than you needed to in your condition - please look after yourself. Or is it possible she may have said it in the moment and hasn’t had chance to say sorry 😔 And explain - she feels like crying as she wants you there - but circumstances have not made it the way she wanted possible. Did she intentionally mean it in a nasty way? If that the case then you’ve gone what you can
