Catullus 89

In this poem, it seems that we have jumped far from where we were in the last poem. Last I heard, Catullus thought he was in love with Lesbia, a woman who only talked negatively of him to her husband. Looking at this poem, it seems as though he is finally in a relationship of some sort with her. Maybe even a marriage? I say this because the poem talks of a love that he wishes would last forever. He refers to it, though, as a friendship he hopes will be everlasting. Maybe he doesn't want to get his hopes too high, or perhaps "ginx" it?
Also, he seems a bit apprehensive toward Lesbia's feelings for him. He prays to his god that Lesbia means the words she says and that she won't take them back. If he truly believed this relationship was what she really wanted, would he be praying to the gods for help? I dont think so..
I understand where he's coming from though. He's in this relationship, hoping to God that the other person feels as much for him and he does for her; but maybe knowing in the back of his head that no matter what, the other person may not even be capable of loving him as much as he loves her. He finally got what he wanted, so he should be happy, and I think he knows that he should feel happy. Yet, maybe he feels like everything's going so well that he should be watching out for something to go wrong to ruin this fatasy that has played out the way he wanted. Maybe at some point, everyone feels that way about someone. Catullus, once again, reached high school students centuries later.
