You should be able to express your feelings to your lover quite clearly and to let your emotions have free and easy play.
This is a decided advantage in a relationship, for in most cases it spares you and your partner the pain of bottled-up feelings or misconstrued emotions, at least through internal misunderstanding.
Since you do not have trouble expressing yourself, you may assume that your lover is the same as you. Here you may be quite in error, and your partner may resent you or simply feel distant, thinking that you lack understanding. The best way to show you care is to get in there and help, even though that may be more trouble for you.
