You know WL going dim doesn't do much to clear up what's wrong. The only way we ever know where we stand is to ask for what we want. I realize that he's not giving you that chance because he didn't listen to how you felt to begin with and now he's punishing you for instead of listening to how it made you feel.
Besides, he still owes you an apology for the way he handled the whole trip thing. Maybe this is just a big huge indicator and a glimpse of what a longterm relationship would be like with him. Could you live with that? Better to know now..........
A GF told me how she uses the 90 day rule for all types of R's. It is easy for someone to put up a front, be charming, etc. for 90 days. After that time, typically you start to see the real person. I have been using it myself with R's of all types including friendships and find that it really works.
You say that you have been seeing this guy for 3 months. Based on your posts, sounds to me like he has flunked the 90 day rule. Perhaps you started posting again b/c you felt in your gut that this guy was not quite right for you. Trust your gut.
Perhaps you should take a break away from him - not to get him back - but to get some distance and figure out if you want this R with him.
