Newbie: Is this MLC and how do I GAL?

[Some Day]

Fellow DBers,

I need your help. H sent me text message today saying he was ready to work things out with me. I called him and to be honest, wasn't sure what to say. I did say that I continue to care for him and have always done so. I said that if he wanted to work things out, I wanted to make sure this was something he was sure of and not because he felt pressure from me or family members. I said that I wanted him to be happy (with or without me) and the last thing I would want is for him to be with me wishing he was with somebody else.

He said he had given it a lot of thought and felt like this is what he wanted to do. He told me he was seeing a psychologist who diagnosed him with reactive attachment disorder (never heard of this), but he was looking to get a second opinion. He apologized for hurting me.

As tempted as I was to start discussing logistics of how this would happen, when he would move in, status of the OW, etc. I did not. I told him about my day, asked about his and kept the conversation lighthearted. I asked him if he had any plans for tomorrow and invited him to go with me to a local park which has beautiful gardens. He agreed.

I'm inclined to take this slow and let him take the lead in initiating conversation of how we move forward. I don't want to put any pressure that will make him run again. What are your thoughts? How should I handle this latest development? How should I act tomorrow when we are together?

PS- I told him about the cruise I'm going on next week. He seemed happy for me but worried (since I am going by myself). He said I should have asked him to go with me. I told him a couple of weeks ago I felt like the last thing he would want was to be trapped for three days on a boat with me
