Attend an ex-boyfriend's wedding

See if he invited you. Go if you are invited, or not if you are not invited.

If you are invited, it means that you have put the past behind you. It is up to you to witness his happiness, and I wish you find your own happiness. You already think of you as a friend. At this time, you can be generous and dress appropriately, which is also a kind of respect for his invitation to you. If you don't think you really want to go, make an excuse not to go. It's polite to be invited by others, and you have to show some respect. Just bless, and if you don't go, explain your excuses or reasons.

If you are not invited, it means that you have forgotten you, or it is no longer important, or you may be afraid to see you think of the past. But the point is that people didn't invite you, so why bother yourself? If you want to see him, go and see his happiness. Generally speaking, it is not difficult to decide whether to go or not. It depends on the reality and your mood.
