You say you are all lovey dovey and an adoring husband with the flowers and poems and stuff. Honestly so are abusive husbands between the bad times. You mention you have hurt her in the past. It could be that you are still in need of healing in the relationship and she may not yet trust you. Poems and flowers are swell, but if they are just used to make up for previous bad behavior there may be no trust and emotional safety to make them feel genuine to her. You need to communicate with your wife, however you two can effectively and safely do that. She might have closed her heart to you if you hurt her badly enough. If that is the case you can not force her back into loving you. I hope it goes well for you.
P.S. Flowers and poems seem a little shallow. Maybe it is just me. After 10 years of marriage I expect more personal and meaningful expressions of love from my husband, but I guess everyone is different.
