what you do now can have a big impact on the next phase of your life! i understand that, in the past, your relationship was the catalyst for discovering and experiencing the world. well, thats over now. it sounds like you kind of know that you're not over your ex yet, and are starting to realize that you're headed towards another relationship with someone. if thats not what you want, or you aren't sure about it, understand that even expressing such won't deter the guy you are now seeing. so, if you are sure you don't want a relationship with him - yet or otherwise, pump the breaks before sleeping with him.

whether you see him or not, here are some things i wish someone would've told me to do when i was in your exact circumstance:

-develop a nutrition and exercise regiment

-apply for jobs for 'fun' things in your area, once you graduate it'll be harder to find time to volunteer/coach sports/etc

-read! biographies, histories, famous novels. sign up for duolingo and make yourself do a little bit each day
