My husband wanted an open marriage and after 5 years I just found out he lied about how many women he was with

I'm just so hurt I don't know what to do. I've been maried since 2018 and my husband asked for an open marriage a few months after we got maried. I didn't want it but I wasn't ready to end my marriage yet so I agreed. We talked a lot about it and set all the rules and everything. He told me about all the women he slept with and I told him about the men I slept with. We were both honest and just wanted to spice up our marriage. <br><br>Everything was going just as expected, we would go out together and flirt with people and I would go home with some cutie everynow and then. But I never broke any of the rules and I thought that my husband didn't either.<br><br>Some time ago I found some messages on his phone and I can't describe how I felt. All the rules we agreed on were just thrown out the window. And by some messages I mean a lot of messages about how he wanted to make me his slut wife and how he wanted to see me with other men. And I thought he was just joking until I found out he was having an affair with a married woman. I wanted to leave him then but he said we could work it out and I was blind. I wanted to believe it.<br><br>But today it got even worse. I was looking for waist beads and found out he spent like 300$ on them for his mistress but not me. And I thought "well he can spend his money on whoever he wants" but then I found out how many women he spent his money on. I lost count after 10. And I'm just so hurt because I wanted to leave him when I found out he cheated and lied to me but I didn't and now I'm just doubting everything. <br><br>We've been spending so much time together and I thought he loved me but after all these lies I just don't want to believe anything. I don't know what to do because part of me just wants to leave and never look back but I still love him. I just wish I could've seen him for what he is before I married him.<br><br>Edit: we recently had a child together and that's why I stayed with him, I didn't want to leave my own kid
