Most Helpful Girl
If you're happy in the relationship and just want to re-connect with some of your favorite people/activities, then that is a very healthy thing to do and could actually improve your relationship over the long run. It's not like you need to spend entire days or weeks apart from your SO- just make the effort to call up friends you haven't seen in awhile, ask them to meet you for lunch/dinner/whatever, and spend a few hours just catching up. You can always go back home to the boyfriend at the end of the night, if you want to. The thing is, healthy and happy couples *want* to be independent of each other... if you have trust, honesty, and a real desire to make each others' lives *better*, then it's important to be your own person and have your own life. Sometimes spending a few hours apart can just reinforce the love you have for each other, anyway!
It's scary to realize how committed and dependent you've become on another person, even if you're actually happy and things are going well. I know all too well how easy it is to get lost in an amazing relationship, believe me, but it's equally easy to re-connect with your old life and bring everything together as a whole.
