If you think you want to have a few months away from the "drama" of his life - then maybe you should take those few months - During those months away, I would suggest taking the time to concentrate on you. What is good, healthy and right for you and your life. Take time to heal about all the things you have been thru -
The saying is very true -
"Nothing changes if Nothing Changes"
You can decide what is right for you and what exactly you want for your life, and how you want to be treated by someone in a relationship.
Sometimes taking a step back can give you a clearer picture if this is the right situation for you or not - Only you can make that decision.
Whatever that may be, praying you find serenity & joy,
Rita
