Love addiction comes from not feeling loved sufficiently. We typically have an identity as someone unloved or unlovable, and we are also unable to love ourselves fully and in a satisfying way. We are unable to sufficiently find love and kindness towards our own emotions, emotional and physical pain, painful thoughts, and general discomfort and unease.
We were not shown how to do this as babies and children. Our parents were perhaps unable to give us sufficient unconditional love, and they were unable to do it to themselves as well. So we didn’t learn it.
What we did learn was to seek it outside of ourselves, from others. Many of us spend a lifetime trying to find love from others, to fill that hole in us through the love of others. It works to some extent, but not completely. It may not be sufficient, it may be uncertain and withdrawn, and since the only real remedy is to give it to ourselves it will never be enough when we try to get it from others.
I was reminded of this when I talked with a friend who is in a polyamory relationship, somewhat against his preference. Polyamory may, for some, be a strategy to find that love. We get it from multiple sources, and we always have one or more backups if one should fail.
It can be just another way to avoid facing the pain of feeling unloved or unlovable, and to avoid the challenge and discomfort in learning to truly and more consistently meet our own experience with kindness and love. The other side of it is that it can provide a setting for us to learn to love ourselves, just as any other setting – whether we are single, in a conventional relationship, or in an open or polyamorous relationship.
