Can’t get married unless I have breast surgery

Okay so I know this post is going to sound silly... but I have breasts that are not like the average kind. & I can’t get married until I have a breast lift / Breast augmentation surgery. I’m very insecure and nobody in my life has ever seen my breasts except when I was sexually assaulted. I’m not comfortable with being completely naked around my boyfriend and I know that when he becomes my husband that has to change but I can’t do it unless I have the surgery. We have a baby on the way so I know if we do get married it will be in the next couple years at least. The only problem is that I have no clue where I would ever afford this sort of thing... especially with all of my money going towards my child. I guess I just need some encouraging words I’m feeling very stressed 🤦🏻‍♀️☹️
