We're all from different walks of life. Some of us grew up in wonderful, supportive families, while others did not. We've probably all been hurt by some form of relationship at some point in our life. You have no influence over your external surroundings. I really wish we could. Your choices are the only thing you have power over. When you're broken, it's difficult to love. If you don't provide your whole self to any relationship (romantic, friendship, family), you'll either (1) ask others to fill in the gaps or (2) shut them out entirely. First and foremost, you must love yourself. Then, rather than looking to partnerships to fix your flaws, you may offer them your strengths. Regardless of the hand life has dealt us, we all have the ability to make this decision.
