I invited a girl I liked to spend holidays at my place and to make a good impression taking her out almost every day. The only thing she paid for was a train ticket and I ended up spending half of my life savings in 1 month (equivalent of 6 months wage). I later found out she was happy to visit me anyway and would be even if we just ordered food instead of going out and stuff. Anyway, we had fun so I don't regret it.
