Wish my husband still went out of his way to make me feel special or beautiful but things change

So we've all heard it before "once you have her, don't stop acting like you're trying to get her" or something along the lines of that. I used to feel so special, beautiful, appreciated, and wanted by my husband but I haven't felt that way in such a long time. I always need constant reassurance about love and appreciatation but I never needed it before. I don't know if it's the hormones or depression but I'm just not happy anymore and being pregnant with our first I wouldn't want to leave, and because I do love him, but I just don't know what to do anymore 😞
