Please I need some advice

Okay so I love my boyfriend like it’s so hard to imagine my life without him and I thought that what we had was special but seeing pics and videos of him with past girls looks like he’s had what we have with every single girl. Like I literally feel like throwing up thinking that what I’ve been feeling is so special is like so common with him. Makes me feel so worthless I’m not really sure if I can get over it or forget about the things I saw. Should I move on if I can’t let this go?
