This post has given me hope. My girlfriend of 2.5 years has had Mirena for about 6 months now. Although I believe she still loves me she has no sexual desires with or without me. I am so stunned with the dramatic turn in our relationship. She too has said I'd be better off without me or that we shouldn't see each other anymore, but she cannot seem to break up with me entirely and always wants me to spend time with her. I wish I could do more for her but the littlest things seem to set her off. I love her a lot and the side effects she is experiencing (no libido, weight gain, headaches, dizziness, stomach issues, mood swings, etc.) and it kills me to see her like this. It hurts me directly and indirectly knowing she is suffering.
She has taken the step to see an OBGYN to talk about her side effects. I hope between the two of them they will be able to pinpoint Mirena as the likely cause and get her back to to girl I fell in love with.
