Veneers

My bf got veneers and they asked for my opinion before putting them on. They said they’d be reshaped or at least I thought they did. Anyways, he got them complete but they look too big for his mouth and I don’t like them as they look horseyish. The reason I feel bad is because they asked me and I didn’t want to be mean so I said they looked fine. I didn’t know what to say considering I know nothing about them. I felt put on the spot and now I’m guilt ridden because I feel so pissed off I didn’t have the courage to say anything. My bf says he’s happy but I can tell he’s not and I feel it’s my fault. I feel he was looking to me for confirmation and I let him down. I don’t know how to bring this up because they are done and cost thousands of dollars and there’s nothing we can do. He just spent TONS of money on this and I don’t know what to say. I really was just happy he no longer has a missing tooth but I think I preferred the missing tooth over this. And yes I still love my man and all that, it’s just everytime I see his teeth because they are very noticeable I’m reminded of how I couldn’t speak up and it keeps fucking with me. Is there anything I can do to get over this ?
