Trying to wwwhhhhhoooossssaaaaaa

I'm a second time mom and my fiance is a soon to be dad for the first time. Although I'm experiencing less extreme symptoms than my first pregnancy the anxiety and mood swings haven't gone anywhere. I'm nervous that he would be too laid back and almost nonchalant about the situation and unconscious of my needs. My first experience was horrible and I just really want this time to go smooth. Please give me some pointers on ways I can just relax !!!!
