I would like to become a good relationship counselor. Please let me know how may i get the required skills and which courses can i take?

Dear Jasmine, 

In reference to you question. Im happy to assist you in answering your question. 

Answer:
To become a relationship counselor, you'll should obtain a bachelor's degree in a mental health field. However, some other establishment they require a master's degree in a mental health field, in addition to participation in an internship or field placement involving direct clinical practice during the course of your studies and the completion of one to two years. 

At the end you have to check the requirements of the country you need to be qualified in.

I hope this clarified your question

NLP or Neuro Linguistic Programming tools and techniques are good skills to have to enable effective counselling and coaching.
