No improvement

My best friend's BF arrived last Sunday. They been together for 6 yrs since high school. Geographically apart for the last four years. Finally, they are together now.
I should be very happy for her. Meanwhile a bit sad for myself. One reason is she will spend most of her time with her bf which means not with me anymore. The other reason........ you know, I feel very sad. Where is my bf? (I reluctant to put EX in the front.) Why he can't be a little nice to me????????.............
