So Iv been with my boyfriend for 11 months now (I'm 18) and I know I love him, and we're going on holiday soon. But there's this other guy, and Iv liked him prior dating my current boyfriend, I liked him for about 2 years, and in the past we've gotten together at party's, and when I was on a break with my boyfriend this guy told me he had feelings for me and we almost got together. It's like I still have a soft spot for this guy, even though me and my boyfriend are good now. I still find myself sometimes thinking about him and what could've been. He's got a girlfriend now but he can still be flirty towards me, and he admitted he had a soft spot for me. He has a bit of a reputation, and I know my boyfriend isn't worth loosing him over. I just don't know what to do, how can I make this guy leave my mind?
