I've been with my fiancé for 2 and a half years now and I love him, I know that he loves me, but sometimes especially right now I get really panicky that he will stop loving me because I'm not good enough for him and it's not fair to him because he's never treated me badly or anything I feel guilty for thinking it but I can't help but feel like he will realize that he can do better than me. Is it wrong for me to be nervous about that?
