@Albertdany,
Dany,
You say that 7 years ago you met the love of your life . That you can not think of anything but him.
Before you met him you were fine. Since meeting him this has all occurred.
If you did not feel the love before, that you feel now, if various things happened before but they haven't since you met him, I understand your "fear" of loss, if he was to walk away.
But, you need to realise we all find someone in our lives that is "it". And, in general terms that is the case, it is "it".
I am glad that you are going to see a professional, I think that you have such a huge fear of him leaving you that you are obsessed with him/love and that fear is what is driving you to the point where you are at.
People walk with us, besides us... It's the fear you have to get rid of.
