Stella this has to be so very tough. I don't know what to say. I do believe love feelings can come back. I believe that with all my heart. I have experienced it myself. That will take time though.
I think your h should be NC with spider, but it doesn't sound like that is a possibility at the moment. Not sure what is with the break-up between them. What is to stop him from getting back together with her?
I think this is going to take time and you need to be loving and supportive at the moment. He won't be pining for her forever.
What does your heart tell you to do?
