my boyfriends first love... advice?

anonymous

i’ve been dating my boyfriend for a few months now. i love him a lot, and i lost my virginity to him. lately i’ve been questioning if he loves me as much as i love him. i keep going back to his ex, and i feel he was so much happier with her. i brought it up to him and he said, “i’m not gonna lie, she was my first”, and that really hurt me because it feels like i can’t compare. i don’t want him to downgrade and move onto someone he doesn’t love as much (me). it seems he did so much for her in their relationship because he truly loved her, i’m starting to think that’s not the case with me, maybe lust or infatuation. i feel if she were to come back his loyalty would be gone and opportunity would take over and he’d leave me for her. i struggle with anxiety and overthink in relationships so advice would be nice to help bring me back down. i just don’t want to keep getting attached to him to have it end.
