I can't stop stalking my ex new gf

I’ve been in no contact for 3 days with my ex. I honestly feel like he’s falling more in love with the new girl everyday since I’m not around and that’s based off her IG and facebook.
Maybe she’s doing that on person because she probably know I’m looking, but it’s burning me up inside to not look at what their up too. I’m giving up hope already because I think he really wants to be with her even though they’ve been dating for three weeks and we invested almost two years together. Can someone tell me what I should do? I can’t stop looking at her pages!

My advice to you is don’t believe everything you see. She may know you are looking and be trying to get a rise out of you.

I figured that’s what she’s doing. So I’m just going to stop looking her page , but it’s so tempting just like not trying to contact him. It’s hard work but hopefully it all pays off. Thanks
