I just got back from my niece's wedding in Georgia, so I'm now all caught up w/you.
First off, very big congratulations to you for your work w/your degree. That must feel like a ton of bricks has been lifted from your shoulders. Good for you!
Also, good news on BF's opening up a bit and wanting to come back in. That is great, but I will caution you like the others have that you'll still need to be very careful, slow and cautious w/him.
Remember, it didn't break overnight and it won't repair overnight either.
As for his "talking" he may or may not ever be able to verbalize what you want him to, so you'll need to decide in time if that will be good enough for you to move forward. He doesn't sound like much of an outward talker about his feelings and if he's not going to continue his IC, he may be more inclined to keep his "guilt" inside and try and "show" you he's sorry rather than telling you or giving you "details."
Then again, you may decide you really don't want to know b/c you may not be able to live with what he tells you.
Again, this will all unravel in time, but make sure for now, you are taking your time as you rebuild your R.
I'm also pleased he's realized he needs to be back on his meds, so that too should really help him...once they kick in in 4-6 weeks, that is.
You sound good and things seem to be starting well for you this summer. Good for you, princess! Keep it up! RTL
