Hello, sorry for the lack of answers for the last few days.
Anyway, here it is: We haven't broken up. He called me about two days after I made my initial post, ready to talk.
I brought up some of the points a few people had about it being a little unfair that he kept the knowledge of his late husband from me after so long, and he agreed. He admitted that he was just scared that by telling me, that he was forgetting Jay. He acknowledged that it was an unhealthy way of thinking about it and that he didn't mean to make it seem like he didn't care.
Of course I also apologized a million times, for snooping through his phone and not coming to him earlier about seeing him with Jay's sister when it happened. We both agreed we had started this relationship too fast, especially for people who both weren't looking for something serious initially. We talked for hours over the phone before meeting at his place. Talked some more, talked about what we want from this relationship and decided, for now at least, to try and make things work. We're both deeply broken people, and we thought that with honesty going forward, we could support and help eachother heal.
Thank you for all your responses, even the not so kind ones. They really helped me open my eyes and think, as well as pushed me to get a therapist.
TL;DR: We're still together, lots of apologizing and crying but we're going to try to make things work.

I'm admittedly still not sure I understand the logic behind not telling you, but I hope the both of you are able to work things out.
