Love and the many seasons that accompany it — happiness the kind spring brings, melancholy that comes in with the rain and the grief and sadness one might see in winters; and you have well blended these feelings with the seasons of your lover - a lady and her many seasons. This is an excellent portrayal of the myriad moods and feelings, and the wait for summer's joys. But isn't love a mixture of everything, then why keep awaiting her summer mood? Why not accept everything? [Do correct me if I have interpreted it wrong. :) ] All in all, a beautiful poem.
