No matter how much they care for the other person and want to be with them, some people simply can't dive head first into relationships. Little things that form intimacy and romance, little acts we take for granted - being close, holding hands, kissing, showing affection in public - they won't or can't do...at least not right off the bat. Something in their past, their experiences, their trauma, or even their personality holds them back. For both them and the person they're "dating," as it were, this can lead to a frustrating experience.
Still, steps can be taken towards letting the walls fall down. Little, tiny steps, but those can mean the world all the same.
One With the help of a partner, one person warms up.
Two Both sides of this couple are learning how to be in a relationship and to be open.
Talking → A relationship can't exist if there's not some communication, so either learn to use your words or become so close you can speak without them.
Spending Time → Even such mundane occurrences as watching TV or cooking together is new ground.
Touching → You might just find you enjoy reaching out and touching them.
Kissing → Another kind of touch, when you think about it.
Cuddling → ...at least they're warm and, hopefully, soft.
Sleeping → You're at your absolute weakest when you're asleep. It shows trust to doze off around this person.
Public Display → It's one thing to be in love in private, but showing you care in public is a different story.
Kind Words → Three little words (more or less) are all it takes. Why, then, are they so hard to get out?
Sex The ultimate stumbling block to some. To be laid blissfully bare is to truly let your guard down.
