Someone once asked...
Someone answered with kindness...
If you're questioning relationships, you might lack trust in the other person and most importantly, trust in yourself. There may have been times where you abandoned yourself to be liked, or where you noticed the harm or inclarity and stayed anyway. If you find a secure place in your own heart, that can serve as the healthy basis to connect to others, knowing your own boundaries and learning to trust them at your own pace without having to rush through things. The pain of being hurt will still happen, but if you know you have your own back, it's a lot easier to handle.
