Jealous of his ex!

I know this sounds ridiculous which is why I’m posting this anon. But I met a guy on tinder things are great. We connect more than any guy I’ve been with and he treats me soooo much better than my exes. He was in a relationship a year ago with his ex for four years. I went to add him on fb and there’s still old pics of them. Of course there’s PLENTY because they were together for long. He doesn’t use fb anymore so I’m sure he doesn’t even pay attention to it anymore but his ex also has photos. No recent pics in case you were wondering. But of course my nosey ass went looking and I can see their whole relationship basically through pics. He got her a ring and a hotel room before they’ve went to plenty of outings together and of course spent so much time and it makes me second guess myself. How can I compare to her?! And what they had. It’s only the beginning for us so I know these so many adventures to come but ughhh ladies I know I sound ridiculous...please tell me how stupid I am 😔
