So Tired of This

To start off with a little context. My spouse has been struggling with a porn addiction for years. Though I only found out about it early last year. We have been trying to work through it and get it him to stop. But with everything that we tried to do to help him stop, he still ends up going back to it. So I question myself, do I just let him do it? In all honesty I'm so tired. I'm tired of worrying about it. I'm so tired of crying and feeling heartbroken over it. My spouse is a good person. Without this one flaw they are the perfect partner! That's why I keep asking myself if I should just let it all go and let them do it. And just forget that it exists? I have other things to worry about l like taking care of our son. And I'll put a (trigger warning) just in case about child loss..But we also experienced a miscarriage too and I ended up in the hospital a few days ago due to blood loss. So I personally have been going through a lot. And with all this stuff going on I definitely don't need this on my mind. I'm not asking anyone to tell me if I should just forget about it or not I'm kind of just venting cause I have no one to talk to about this. I'm just asking myself. On what would be the right choice for my mental health in order for me to just move forward from all that and focus on the now.
