My boyfriend of 14 months now and I go out with his friends (a couple) from time to time. They have been friends for a long time and every time we have a conversation, it is between the 3 of them and I am totally out of the picture. They look and talk to him only. As much as I try to strike up a conversation with them, they go right back to talking to my boyfriend. I don’t have problems with other people, just this couple. Is this rude or to be expected?
