Long term relationship come to an end

My 3 year relationship has been over for a bit more than a month now. I’ve been dating back to back for the past 8 years with no room to be single until now. I very much want a future such as marriage and kid but I’ve never had a chance to experience being single for more more than a week, let alone over a month. I know people have their phases of having fun and what not. It’s a dumb question but how can I experience letting lose with no attachments for this year? My past two relationships were toxic and I’ve been in school full time (graduating with my bachelors this year- continuing for my doctorates!) and now dealing with a full time job. Your girl wants to try something different, at least once by ‘wilding’ it up. Suggestions?
