No one can promise they’ll never hurt you, because at one time or another they will. The real promise is if the time you spent together will be worth the pain in the end.
Stop trying to ‘get it together’. The biggest lie we’re told when we’re growing up is that soon as we’re adults, as soon as we’re in college, finish college, get that job, have that steady income, find that someone special, ‘find ourselves’, find that perfect house, get that retirement fund, have those children, everything will fall into place. Here’s a secret: it won’t. Every new development in your life, good or bad, big or small, will come with its own very special set of challenges. The sooner you accept that, the better off you’ll be.
