Love in Buddhism is compassion. My own heartaches always lead me to deepen into my intention to be a more loving human. While I'm healing and integrating the feelings of loss back within I try to focus on sending loving-kindness to others. Sure everyone wants love but much like happiness, it's already within you to be happy and its the same for love.
I'll give you the buddhist answer for once: Love. Just love yourself more. It will all fall into place. When you have love for yourself, you will have love for others. Don't let anyone make you feel bad for not being emotionally ready to share that love. It's okay to keep it to yourself. Personally, I find focusing on myself helps me serve others best.
If you don't know how to tap into the love within my suggestion is practicing Metta(s) for others. A Metta is a type of meditation. In this meditation you learn to love yourself through connecting and experiencing a sense of unselfish love toward another. Think of someone or something that easily inspires feelings of love, compassion and warmth. It is the best if you can use yourself as the object for compassion. If it's easier you can use a friend, family member, a child or an animal as a benefactor. Once you find your object, you focus on your feelings for them and let the love grow and expand naturally. You can think 'may you be happy' or 'may you be safe' or "may you be well' and if your metta is focused inward then say "may I be happy" and so on.
Finding love within opens the possibility for true love or compassion.
Here’s a lil ol story about love, the wanting of love and being a little unsure of love. Just remember, everyone deserves to feel love.
What is it honey? Tell me about it then. Love. What about? It hits you that’s for sure. Knocks the wind out of you if you’re not careful.
