i need a wife
Hopefully you don't really NEED a wife (I suggest to start over with a nice girlfriend first - there's wives you can buy over the Internet, but... well....idk) but just WANT one?
Get life working for yourself, enjoy it, be the best self you possibly can and you will automatically emit a positive attitude to the world. And maybe there's the right person around you to be attracted by this.
If not, enjoy life either - we usually tend to hunger for the things we don't have. Don't let this ruin it for you. You can't always get what you want!
And if you're sad, stop being sad and be awesome instead (e.g. 50 Burpees is a great sadness remover)!
