A second love?

Oh my gosh... my eyes have gone astray they've met yours and now I can't keep my feelings at bay.. but wait, he's still here my love, the one I love he's still here what do I do? i know the risk is so great I could loose both of you. Is having a second love okay? Is this love I have even true? what do I even do? Because you have me absolutely swoon But he is the one who loves me too...
