Can you ladies help me make a finsta to lurk?

Story time: about a month ago I was looking at my husbands Snapchat memories on his phone and he got a notification friend request that said added by number, I pretended to not see it & go about our day 2 weeks later I went to look and he didn’t accept or deny it was still there so I looked up the Instagram handle on Instagram just to see and the profile was public but no photos so I looked at their tagged pictures and found my way to another profile who had a picture of my SO and her casually. Still I left it alone because I was trying to make sense and put the pieces together on my own, but the next day both profiles blocked me, I was careful not to leave any tracks, silly me didn’t even screenshot what I had found. I feel like if I go to my SO he may call me crazy or deny so I want to make my full case and have all my information on hand before approaching him.

& no this is not a friend, I’m not insecure, I’m trusting my gut.

I’m just looking for ideas, I was going to make a dog page but I don’t have a dog and I’m honestly not good with the cheesy dog captions. If you have any photos I can use to make it more believable please leave them in the comments & one I’ve made my page I will add the Instagram handle so you can follow if you want to help in that way!! Thank you in advance ladies!
