I've been with my boyfriend for about a year and a half now. He's a very outgoing person but with all that said, he is such a flirt.
He is a musician and he wants me to go to most if not all of his gigs to watch him play. He knows that I'm watching him and he loves that I'm here, but he flirts with girls right in front of me! I know that he loves me and would never cheat on me, but it crushes me every time and makes me second guess myself.
I tear myself apart comparing myself to these girls, wondering if they have something that he secretly wants. I really do think that this flirting is part of his personality, but it's totally starting to affect my self-esteem. What do I do? Do I confront him about this? How do I tell him how I feel without sounding like a jealous girlfriend?
