Maybe he was distracted by something else? I'm sure your H has a lot on his mind right now as well. I'd encourage you to use the ACT AS IF technique in DR when you see or talk to our H. Especially if you have a tendency to anticipate how you want the interaction to go, or be disappointed, maybe you can act as if its great to talk to him.. hear from him. Be positive! I find that this works WONDERS with my H. If I'm positive and upbeat, he's more likely to be excited to talk to me.. and if he started the convo on a down note.. his spirits are lifted by my attitude. Then he truly is excited to talk to and see me because I become someone who makes him feel great when he's with me. It's hard to maintain (especially when you're hurting and doubtful), but it does work wonders for the PMA.
Good luck! Try not to get into H's mind too much right now (and here's the disclaimer that I can dish this out but have a hard time doing it myself!). Burgbud made a comment on my thread about being a person that attracts their S through the way we act and improve ourself, rather than trying to control their partner. The more we can attract them through being the kind of W they need.. the less we'll have to worry about what their thinking, who their thinking of, and if they are here to stay. Also, working those changes in ourselves, benefits us quicker than waiting on our H's to make us feel happy and secure.
