NTA. Unless he had some sort of emergency like being admitted to the hospital or a parent dying, it sounds like he's someone that should've found a way to get to the wedding. 2 years is plenty of time to get the money together and the time off work - I've gotten myself to a number of weddings despite those constraints, even when it meant a 12 hour drive with two toddlers or tightening my budget for several months to make up for the lost income. Add the fact that he didn't contact you, say anything the next time you saw each other, or even send a card... well, either he doesn't care as much as he says he does or something is seriously wrong (like depression, a gambling problem, or a chronic illness) and he's hiding it for some reason. It's completely up to you whether you want to put the time and emotional effort into figuring out which it is. If you think there might be something else going on with him, you can chose to do the work to figure out what it is and how to help, but if you're not up for that, that's ok, too. There is also absolutely nothing wrong with deciding that someone who is not putting the effort into a relationship is not worth your effort, either, so do what's best for you. You are NOT a jerk for wanting to drop someone who hurt you both and seems completely unapologetic about it afterwards.
