Dear Bliss,
Sounds like a bit of a values conflict to me. Certainly there is a self - esteem issue but the truth is that you need to choose a partner who shares a similar values system and clearly this fellow does not. He is only telling you what you want to hear to keep you from leaving him. Make a list of your values and base your decisions in life on those values and you will always stay true to yourself.
Reiki one will definitely be a good start to your self love program. My advice to you is get rid of the boyfriend and work on your self esteem. Ask the universe to send you the right information and support. Don't get involved with anyone for a least a year or two of self-healing and self- exploration. This is the only way I know of as a trained counselor that you can attract a different type of boyfriend. You must become whole. A book I highly reccomend for your personal empowerment is " The Secret".
Love & Light,
Whitelace
