Do you think you still have feelings for her? Will it hurt to see her when I leave? Can you be happy that she once dressed someone in a wedding dress? Generosity is easier said than done. You need to grasp it yourself. Only you know what you think in your heart. I just hope you can be happy.
I think: men should be generous. After all, the woman who once loved you is right, and you will find your own happiness in the future. I think she will bless you too.
If you have a girlfriend now, make it clear in advance. If not, treat it as a friend, bless you, give some help to those who can help, and then explain to her, and try to go as little as possible next time. To be a man, you must have responsibility and courage. Face it bravely, and everything will be fine.
