Love but no lust

I would appreciate any advice. My wife and I, in our early 40's, have been married for 15 years and have two wonderful children. 2 years ago she told me she wanted to explore opening our marriage to other people. I reluctantly agreed after she said it was something she felt she had to get out of her system. To this day, she has only been with one other person since then but fantasizes about many others. I haven't been with anyone else but our agreement was that we would experience this together. So, this has kept our exploration to threesomes(me, her and another male). This hasn't heppened in over a year now though. I am all about having fun but I believe it has to be fun for both of us(and I don't neccessarily mean me with another person).

Lately, I feel like it's me who is keeping this relationship together. I know it sounds like she is a woman that has fallen out of love but she assures me that is not the case. I love her very much but I told her if she feels like she doesn't belong with me, then she can leave. She tells me she wants to be with me for the rest of her life. She says she loves me but doesn't lust for me, which explains her behavior. Thankfully, she is very open about the way she feels and doesn't want to go behind my back to do things. My question is... What can I do to return that lust in her?

I feel the need to always be around her. Should I fight this and make myself scarce giving more attention to the kids or myself? Would this make her heart thrive for me more? I do not want a relationship that is all about sex but... I want to stop feeling so alone when we are together. Tweet
