My current bf and I have been dating for 3 months now, but I feel like I was just a second choice. He really liked this girl and also liked me the same time, but when things didn't work out with her, he went after me and I have just been thinking about it lately and I feel like I'm just the 2nd choice and I'm ashamed of it. what do I do about it? I don't want to be someone's 2nd choice, but I enjoy being with him
