Hi savemeplease,
Welcome to HW and the A/P forum. You are among friends here. Anxiety can make us constantly question ourselves, and those around us. I know that when my anxiety is high I can become unreasonable with my partner and drive him nuts needing constant reassurance that I'm not annoying him with my anxiety. What a catch 22!
I'm not a relationship expert but in this case I would sit your fiance down and be 100% honest about your concerns. Tell him that you feel anxious that he is losing feelings for you, that it makes you feel upset. Do not use any blame, be up front about the fact that you are worried about his lack of action in regards to you moving in. Ask him how he really feels. It has to better than wondering and making yourself upset every day not knowing.
If this is too confronting, write him a letter. It's easiet to speak the truth, and not say something you may later regret! I know this may seem daunting, but you need to know the truth so you can move on if need be. Most likely he was a little snubbed when you first refused to move in (for very honouable reasons I might add) and now he is scared YOU will reject him by not moving in. It may well be that he has the same insecurities as you. Talk it out, clear up how you are feeling. You will feel so much better.
Again welcome, I look forward to getting to know you better.
