My DP and I have been together 2 years. I'm still 'in love' with him, feel a spark, get butterflies, all that. He still does little things to make me feel loved and says it regularly, but he seems to have lost that 'in love' feeling. He rarely kisses me and they're just pecks, has no interest in sex or showing any physical affection. It just feels like something has changed for him but I don't know what.
