I fall out of love after mania and meds

I met a wonderful guy while I was in hypomania and fell madly in love. After a month I went into heavy mania and was hospitalized. Until then I took antidepressants and started taking medicines for bipolarity (cant post the name of the meds). After hospitalization I totally lost my libido and the passion for him passed. Has anyone ever been through this? I keep wondering if my initial passion was caused solely by hypomania, or if after I got out of the mania crisis there was a chemical imbalance in my brain that made me fall out of love, please let me know if any meds you take made you feel this way, numb
