I don't know if it makes sense to you, but at times I find myself caught in this web of being happy and yet jealous at the same time. The thing is, it's getting more frequent.
Every girl reaches a point in her life where she starts dreaming about The One. Okay, not the Matrix, or God, but the significant other in her life. Some girls are fortunate - they don't have to dream much because they've found him (or he's found her, if you look at it that way). But on the other hand, if you've reached the age where everyone else is hooking up / has hooked up / is going to propose / get proposed to, and you're still single...
It's funny, I suppose, because I am happy that they are together, and yet I am jealous because they are. Ah, love.
