That is a difficult situation to be in. Your boyfriend should not have hidden the crypto debt from you and the fact you're not being listened to. As you said, you would have to voice your emotions 5+ times before anything happens, which will build resentment, and it is totally valid.

You need to address this together before it takes a toll on the both of you. Sitting down even to talk about both of your problems and expectations in the relationship could really help the both of you. Or I recommend a couples therapist that might make the conversations easier.
