I know what you mean about being afraid to feel that way again. I have strong emotional reactions to memories, and it is really hard to read over my journal--especially when I see parts where I wanted to believe what he was telling me and I now know that it was all lies. It helps to focus on the bigger picture. And a glass of wine doesn't hurt either!
So it sounds like his LL may be acts of service. What can you do for him that he would recognize as an ILY?
