Spend the portion of the $500 you spend at the bar / restaurants on active hobbies. Take classes like yoga, kickboxing, or CrossFit. Join a rock climbing gym or spend the money on travel to local hiking destinations, invite your friends. Think of other hobbies which include group social activity like dance lessons, photography club, indoor soccer, etc.
Obviously these specific examples are not the point ... the point is don’t look for friends/ love at a bar or you will have friends or a lover that goes to the bar all the time. $50/wk for ______ lessons sounds expensive, but it’s cheaper that $500/mo on wining and dining, and will be more fulfilling.
