As a lot of people has already told you in the other comments, your boyfriend is showing you who he really is. I'm 29f and I was sooo excited when I first got my braces on september of last year, I immediately sent pictures to one of my dearest friend who reply to me : 'you look beautiful, now you have to smile to show them!'. My friend died in an accident the day after. I was so sad those first few weeks I barely felt any pain or discomfort, the lost of my friend numb all my physical sensations. I don't usually write about this but I thought it may help you because you seem really anxious.The people that loves you will support you and encourage you at all times, and the thing that truly matter in life are sharing moments with them. I hope you get to a moment when you can appreciate how lucky you are for having the money to cost braces. I keep asking for new colors every appointment and I smile much more than before.
