Smiling she remains

Sorry but I'm not even sure the above people actually read the poem. At least to me one liners usually mean they didn't bother taken the time to read or even understand the poem. Or maybe thinking the person will return the favor and comment "Nicely" on theirs.
"She lays in his arms for hours
but her thoughts lay with another"
This is a common romance line. Believe me you might find other lines just the same in some other poems here. Maybe not the same wording but same basic idea.
"mourning for the death of his love
he found a new love to give his heart"
This might be better if you changed the second line or expressed how much something might have hurt. It just seemes almost cliche and I'm sure you wouldn't want that.
The final two stanza's is where I got confused but I assume that you meant that her twin is really the fake happy side of her. Overall decent poem but maybe becareful of people who don't take the time to say why they liked your poem or how exactly they could relate to it/
