I feel you, girl. Sometimes Damian gets mobbed by fangirls at gamer events, including ones at which I’m not in attendance. It initially made me uncomfortable to think about that, but then I remembered that I’m the one he’s chosen to be with and I’m the one who he comes home to.
Look, when you really ponder it, there’s no sense in worrying that your partner will be tempted by other suitors – because a) the desire involved is theirs, not his, b) you’re his girlfriend and he must like it that way or he would make some changes, and c) if anything were to happen, then you’d know he was a sleazeball and not worth dating anyway. Presto, magic!
Instead of focusing on your feelings of jealousy, try to focus on your feelings of gratitude for being the girl who has what so many other girls want.
