Oh my...thank you for your generous accept and bonus.
The question about love requires a philosopher...well, PhD is a doctorate in philosophy...so I will give it a try. What is love?
"Love cares what becomes of you because love knows that we are all interconnected. Love is inherently compassionate and empathic. Love knows that the "other" is also oneself. This is the true nature of love and love itself can not be manipulated or restrained. Love honors the sovereignty of each soul. Love is its own law." I wish I could say I wrote this but it is from a book called The Seven Natural Laws of Love. http://www.psychologytoday.com/blog/love-without-limits/201111/what-is-love
Love (and jealousy) are feelings. Your feelings are your feelings and they are neither right or wrong (I did write that). Feelings can't be turned on and off. If someone said to you "Stop being jealous"....can you? It is about trust, isn't it? In order to change the feeling, you need to change the way you think. (This is called cognitive behavioral therapy in out profession). So if you can change your thinking to "I can trust her. I do not need to feel jealous", you might be able to change this feeling but it takes some work. But trust is only built over time. Trust and enduring love (not just infatuation) take time and from a psychological perspective, it may be too soon to predict if this relationship is the "enduring love" you are yearning for.
Remember, this is the philosophy of an American, woman, psychology expert. The perspective of a European, male, psychic may be very different. These are not black and white issues but definitely interesting topics of discussion.
Again, thank you for your generousity,
