Is There a Role for Behavioral Activation in Relationships?

So i'm going to ask um a follow-up question there that feels related which is it's a topic that that you've written about. Is there a role for that kind of attitude in in relationships and i guess not just physical intimacy although i'm sure that's where most people's mind goes but just like in the grind of showing up for your partner day-to-day when you have been married for 10 15 20 years  it does go along with what we were saying before about putting in some energy. I do think especially in relationships as opposed to depression like it can take a lot longer because you're sort of battling your own internal demons, right?
