It is normal and even mandatory that parents give positive, appreciative feedback to any growwing child. People do this in different ways so whether one has a very emotional style or not,he can be a good parent. But being "emotionless" i.e. deadened, without vitality or withholding is definitely not good. If that is an accurate description of your partner, he needs help and you should stop restricting yourself. But make sure that that rather extreme description of him is accurate before you read him the riot act. Some people express their emotions in subtler ways than others.
