For this matter, I personally suggest telling them about the marriage and inviting them to your wedding, but it doesn't matter if she has a lot of inconvenience. When you take your wife to travel there, invite them to dinner. You told them there was nothing to say, and at the same time you said it didn't matter if you didn't have time to attend. If anyone doesn't want to join this group, he won't be embarrassed if you give him a reason.
I feel it.
The key is whether you still want the money. If you don't need money, you just don't want it, and there is no particularly good relationship between your former colleagues, then there is no need to tell. It depends on the relationship. If you have a good relationship and have had contact, you can invite others. If you haven't touched it, your sudden invitation will embarrass others, so this kind of thing depends. I invited my former colleagues when I got married, because we have always been in contact and have a good relationship.
Let me know if you still want to pay for this part. After all, it is not easy to earn money by working in this society, nor is it caused by strong winds. Of course, I think reasonable people will understand this psychologically, but it is estimated that some people will play the fool and be fully distracted, and this part is wasted. If you have a good relationship, such as helping you at that time, it is best to inform you, but be sincere, don't take money too seriously, and it is best to give gifts to your post after marriage. Some very close friends have sent invitations, and they will thank you for remembering this friendship with your colleagues. The relationship is average or not. I suggest not to send it. If you do, people may not come. If you come, you might mind paying.
