How do we know you are focusing too much on H and not enough on you?
In your post you prove he is no where near his answers, if he is MLC. MLCers don't run around like rock stars and tossing around references to when they plan to return. They do run around like rock stors tossing around all kinds of nonsense and crap. MLCers don't know when they will return or if they will return. They are totally lost in their own fame.
Only when they hit bottom can they honestly speak of coming home with a conviction that they will want to stay.
You seem to have been believing him for a time only to be let down. Now you are questioning his statements for good reason. What you say to him is up to you but what you say to yourself is more important. You can show him freindship and acceptance, but you need to teach yourself to say "fine ... whatever" inside your head when he talks. His words have no home. You must protect yours.
When you see a hole in his story or thinking you focus on that and become hurt. They don't lie to hurt you. They lie to make themselves feel better. Don't let his words hurt you more or longer than you can help. Focus instead on yourself. As you learn to let him go and ignore his nonsense, focus on your power to do so. Focus on your ability to survive the unexpected, instead of unexpected pain.
Focus is so important because we all eventually learn that what we focus on expands. Focus on what you want to see grow and make you better or stronger.
