Cheating husband

I was in long distance relationship and we were married and had a son. During that time my friend had told me last night when we were away from each other he asked her for a girl to fuck for his best friend. She gave him the girl that is available and turns out that the prostitute recognise him cause she was my friend somehow at high school. And after that another story she said that he was going to rape her in a hotel where he said everyone will be there but it turned out different. He tried to kiss her and she refused etc.. so there is two story from her side.

My husband told me about this incident when we reunited after the long process of long distance relationship. But, his version was that she offered him a girl cause she needed money. He said no and he also said he would not dare to do it cause she would've tell me like there will be a chance she would spill it to me. Anyway contiuing from that he said that she threatened him she will tell me that he cheated on me and I would've believe her straight away saying made a lie about him. So he was afraid that i will believe the lie and he asked her what she wanted? Money. So he send her once for the amount she wanted and tried to ask for another he said no. Again she threatened him back and he said go ahead but during those times she never once reacher to me which is so easy to get to me.

Now her excuse is she didn't want to tell me previously because she didn't know what to do and now she revealed it when i am 2 months pregnant with the second child based on me confronted her with his version. I dont know what to do and who to believe. He cheated on me once before we got married and found out from an anonymous texted me randomly. That time he confessed straight away without any hesitation. So this time around he is so persistent meaning there will be no way he would say its true and he would rather end the relationship regardless.

Tell me what you think cause i am very devastated.
