My friend sent her a short message when she got married.

An unfamiliar friend, she's getting married. He sent you a message asking you to attend her wedding, but you felt particularly uncomfortable because you didn't ask him to get married. I don't think so. You can go to her wedding happily and let her feel your support for her, but you still don't have much feeling for this friend. You can let the gift go with you, and we don't have to go, so we can meet less, because he has already. It's hard to say when we meet again. If you don't go, you can ask a third party to explain to this buddy that she didn't call you when she got married, so don't call him when you get married, or he will feel embarrassed if you call him. Maybe this buddy will be relieved, and he will not necessarily investigate the reasons and responsibilities for your non-participation, nor will he have too much enthusiasm for you. You should think clearly.
