Get into the experience with the focus of moving on after break up, learning about yourself and progressing, not about venting anger to your partner. Venting can only make us feel good momentarily. Check out the tips below which I think is more or less similar to the book I mentioned.
Love in Ladue
Have you ever been in love and committed to someone so much so that you know if a moment called for it, you would happily give your life for that person without even thinking first? – http://ladue-frontenac.patch.com/articles/love-in-ladue-breaking-up-is-hard-to-do
I think counseling is not necessary because it will not help you much unless you are really seriously depress. But if you can learn to control your emotions, then a reputable and inspirational book will probably give you much relieve. Furthermore, it won’t cost you a bomb and repeated visits to your shrink. No harm paying an affordable price for a book first rather than making a drastic move.
