Since it has 'been over a year' sounds like 'feelers' to see if his 'old cushy nest' might be available again and what better way to get back in than manipulation?
Sweetie, remind yourself he is an addict! He doesn't know how to love himself, so how can he love you.
His cards caught you by surprise, and yes, I think in the back of our brains we really want them to be well, to be different, to be what we 'hoped' they were ............................ THEY ARE NOT.
Look at this as another attempt to find his enabler and let it go, let it go for your own peace of mind and serenity.

BTW Hope you have a really good Birthday.
