I've been with my boyfriend for six years now; we met at high school and stayed together throughout college even though we lived hours apart. I'm now 23 and we are finally moving to the same city, but not living together. The problem is, that for the past few months I've been having doubts. Firstly, I never planned to only be with one person my entire life — it just turned out that my first boyfriend was so great. Secondly, even though he's perfect and we've been through so much together I think we've lost the spark; I find it a chore to speak to him sometimes, sex is dull even when we try and "spice it up," and I find myself making excuses to see my friends instead of him.
I feel like maybe I need a break from him, but I'm scared that he is the best thing for me and I'll lose him forever. Any advice?
