I am sorry to hear that.
No one here can tell you what to do. Sure, it’s easy for us anonymous internet people to tell you that you must “certainly” do things that are very difficult. But you have to live with the consequences. If it were me, I’d view it in terms of several options pertaining to a couple of different questions.
First, there is the matter of whether to “report it” or not. I’m not the type to advocate writing the bishop every time a priest rubs you the wrong way, but a priest openly admitting attending gay weddings is a pretty serious thing. A letter to the bishop would not be out of line and I would encourage you to seriously consider it. And, yes, it would likely come back to you, whether it was anonymously submitted or not. I would never recommend writing a letter anonymously, though. Anonymous complaints are taken far less seriously. So you have to decide whether you can live with that. Obviously, if you were switching parishes, it would be easier to live with it because you wouldn’t be there anymore.
Second, there is the matter of where to go. Again, it’s easy for us to tell you not to go back to that parish, but you are the one who would have to drive to the next parish, which it seems from your previous posts is not that close by. I can understand not wanting to stick around, but I know that I would not allow myself to be easily scared away from my parish. A good pastor is a good thing to have, but even if he’s less than ideal, he is not the sum total of the parish.
Either way, I feel for you. It’s going to entail a bit of mortification on your part however you slice it. One thing that is not an option is to stay away from Mass on account of the priest. No matter what he is putting out there, the Eucharist is still there.
I’ll say a prayer for you.
