Fake Snapchat husband fell for it

I know this is so wrong but I made a fake Snapchat to see if my husband would reply and add a fake girl and he did I don’t know what to think? Although he did say he was not single? But then he said is this a fake profile my family pranks me a lot and I said I can send a pic and he said that’s up to you and then he replied saying goodnight to this fake person that’s me? Ugh I’m so mad I shouldn’t have done this but we are having issues and it just sucks he would do this

Update: My husband has cheated and we are having issues so I wanted to see if he would talk to other people he deleted me from Snapchat and told this fake profile he was having complications with his girlfriend and that she could text him I mean that’s the part that upsets me he doesn’t even know who it is and he is giving in that easy to even be sneaker he said he could only talk from Snapchat no phone numbers y’all can’t say there’s not someone out there that would feel this way I just wanted to know where we stood so I can divorce plain and simple
