You should never say no to love.
Reason 1: Love doesn't take no for an answer. Love doesn't go away because you think it would be more convenient for you if it did.
Reason 2: You're an idiot if you allow (or push!) someone you love out of your life just because you're scared.
Reason 3: Love is always good. Even if you can't figure out how to work it, even if it's inconvenient and uncomfortable. Be patient and you'll figure something out.
Reason 4: The more you experience love the bigger you find it to be. More facets and permutations are revealed to you. You recognize it better, sooner, when you encounter it elsewhere in your life. More love is better than less.
Reason 5: Would you say no to fifty bucks? A cookie? A beer? Love is SO MUCH MORE IMPORTANT AND BETTER THAN MONEY OR FOOD OR ANY OF THE OTHER THINGS WE DISTRACT OURSELVES WITH. SAY YES!
Say no to love and you will just suffer the pain of realizing that you made a huge mistake. You've probably done damage to someone you care a great deal about, you've missed out on some amazing opportunities and there's nothing you can do to fix it.
Love is scary. Love is the best thing in our lives. Love is the only thing in this life that we can keep. Love will mess you up and hurt you and heal you and keep you going. It will save you.
You're going to suffer either way. Life isn't about convenience and security. Life is suffering. You can choose beautiful, meaningful, life enhancing suffering or you can choose stupid, useless suffering that helps no one.
I'm talking about love, not attraction. Big tidal wave love. I'm not saying you should hop into bed with whoever appeals.
What I'm saying is don't run away. Let love happen even if you don't know what it's going to do or where it will take you. It will take you somewhere good. The ride will be worth it. Be brave.
You don't really have a choice after all. Love will find you and overcome you.
