Sorry this is long but this is bothering me. I like the advice that you guys give and really respect your ideologies

Before I married my wife, I made it clear to her that if she was dishonest with me it would not work out. she saw it as an ultimatum and it was - It came up because I previously caught her trying to hide messages to a guy who I had asked about before. I know that he's a friend and that she doesn't have any sexual history with him. Long story on how, but I definitely know. I also told her at this time that I would not be OK if she talked with exes, followed any ex's on social media, or searched for them. They're gone like mine, and this is a boundary for me

Heres the scenario - There is a guy she used to talk constantly with and flirt with, and who she met one time. I knew about him, but she didnt know i knew. After we got married I went trough her phone again (I know, beta trait) and saw that he was following her and she was following him on Snapchat. No communication though, just a sole message from when they stopped talking. I let it sit for a couple of months before confronting her because I wanted to see how it turned out. When I confronted her she had blocked him by this point. She swore up and down and on a dead relative that she wasn't following him (dramatic) and I told her that I saw it myself and that she was following him until recently

Outcome was that she finally admitted that she was following him because he ghosted her and she wanted to show him how happy she was with me. She also stated that she didnt lie when she swore to me that she wasn't following him because she wasn't following him at the Time, and that the only reason that she recently blocked him was Because he was going to be at a wedding that we were attending. This whole scenario is childish, but she was trying to make a guy from her past jealous and outright lied about it. again, i know for a fact that she has no sexual history with him

So now here I am ready to contact a lawyer to draft up divorce papers because I can't trust her and because I would consider this cheating, but I want to get some advice. I broke up with her and meant it, and I stopped arguing because its over in my eyes but she is still trying to "save" the marriage. I'm already thinking of getting back on my game with other women. just trying to get some input or advice

Tl;Dr wife outright lied to me about a guy she used to talk to
