Summer time and the living is... easy?

I'm sixteen days into summer and I feel no sense of freedom or elation, all I feel is I'm wasting away. Do you ever find yourself regretting something suddenly or not so much regretting, but wishing it had gone a different way? Lately, I've been feeling that. There's a person in my life who I used to love, and who I think. . . used to love me, It's been a long time since we've seen each other, but once upon a time we were together and I was happy, very, very happy and when we broke up it didn't hurt me because I wasn't in my right mind at the time. Now, I'm with someone else and they make me very happy, but sometimes I wish I had fought for what could have been. Sometimes I still miss them even though it's been years, sometimes I still think of what it was like to kiss them, and the fun we had together. But now it's too late and sometimes, I still want them, and sometimes I wonder do they ever think about me?
