I'm sorry to hear that. Is it possible that it's not really about the money but he is anxious about spending time with your family (being judged or not accepted)?
Or, is it possible that it is about the money, but the trips last summer were paid for by his old boss?
I feel like now, when you are actually in a relationship, is when the DB techniques are really useful. So many of us are just trying to get to where you are... but as I've heard, the piecing and reconciling is even harder than what came before that. It is so easy to fall back into old patterns.
But one person can change the dynamic. What can you do differently this time? What effect might it have if you "let him off the hook" resentment and anger free this time?
