wanting to come out

Hi everyone, my name is Grace and for as long as I can remember I've always been attracted to both guys and girls. I'm currently in a relationship with a guy, and I love him to death. But there is this part of me that feels like I need to come out to my friends. My best friend is lesbian so I know all my friends will except me, but I'm in a long term relationship and I don't know what to do. I don't want my friends to think I'm unhappy with him, because I'm so happy. But I feel like this part of me needs to be free. If that makes any sense lol. Also. I've never been in a relationship with a girl and I've been in many relationships with guys, so what if they think I'm just confused. I'm not confused. I know who I'm attracted to. I just really need y'all's help! Thank you!
