How do I let go of the love of my life?

Day by day, honey! It is very hard to get over this. But you eventually WILL! I promise! Try to look at this in a different perspective. Instead of it being a negative like getting over it, try thinking of it as moving on. For the first few months try not to answer his calls, unless you have children together. The least contact, the better. Don't check his FB or status updates for a while. It will only hurt to think he is just "living life" while you are hurting. Try picking up a hobby to occupy the time you used to spend with him. Spend more time on bettering yourself. Get a facial, new haircut, or new outfit to make you feel good about yourself. This was a long relationship and frankly, in my opinion, not completely over yet. But ask yourself,"How many more years of the up's and downs that come with this relationship do I want to endure?". That may or may not give you motivation to move on. Counseling is very good if you can afford it or have insurance. Friends are great outlets too. They are supportive and give an outside perspective on your relationship. Good luck!!
