help.

I really didnt know where to post this, so i just decided to put this in here. So the other day i was on my boyfriends snapchat, and i acidentally hit on this one girls name, and i saw a message from my boyfriend to her saying "damn girl😍😍" but there were no like other flirty messages, or he doesnt even talk to her alot, just on the pictures he slides up on. What should i do? I just dont want to lose him, im still having trouble with relationships due to my last relationship. I know my anxiety has alot to do with this as well.
