He may or may not believe this, it's hard to say really.
One thing to keep uppermost in your mind, I believe, whether thinking about giving him a letter or being around him after you leave is this.
- he was willing to try and be a better man for me,
- him telling me to just 'get the **** out'.
- Followed by a text this morning that said 'I love you.
These actions are all from
the same person.
It's not just that - oh he just said that when he was drinking. Oh well now he's sober again and feeling bad - oh he is drinking again.
First of all, he is never "sober", his thinking is skewed. What person would tell you to F-off then tell you the next day they love you and wish you would try.
Someone off balance mentally. Try not to separate him in to two ways of being. If you handed him that letter today and he read it calmly and said he needs to think about it, for instance, that same guy will be drunk later and you don't know what his reaction will be (then or even sober-ish).
If he truly doesn't understand - that just means he is completely out of touch with what is going on/what has gone on, you can't correct that type of thinking really.
