You might be doing yourself a favor to skip the birthday party this evening. It's going to take you a while to get over the grief of this loss. You had hopes that have been dashed. He wasn't the right guy to invest your hope in, but you didn't want to face that . . . until there was no avoiding it.

The mutual friends you shared with him may well be more his friends than yours. You need to travel in different circles. I believe you may not have really had that much in common with the kind of people he fits in with. Now you are free to find those who share your values. For now, you are lonely not just for him, but for the social circle that came with him. Don't look just for a boyfriend, but for friends. If you are a good dancer, you have a tremendous social asset. You need a girlfriend you can go out with to venues where there is dancing. Then be slow to parner off with anyone, until you know what the person's character is about.
