The pro_stitute I met is better in bed than my pregnant wife.Should I dump my wife ?

Please don’t judge me. I’m a 40-year-old man and my pregnant wife is in her 30s. We travelled to Zimbabwe on holiday for the first time eight months ago where I met a 19-year-old prostitute and, to my shame, I think I’ve fallen in love with her.
I was at a low point – my wife is wonderful but she’s become very cold of late. I know she’s pregnant, but she doesn’t fancy me now and I have to say it’s mutual.
I was out on my own in town when I met the Zim girl. Talk about beautiful and exotic – she looked other-worldly. She turned me on so much and we had the most mind-blowing sex – the type of s*x I’ve only ever dreamt of before. Although I did pay her, I felt there was also a meeting of minds and that she understood me.
We met up a lot after that. I couldn’t help it – she was so warm and inviting. When we made love it felt like heaven, so we did it many times and even thinking about her now I can’t help but get turned on.
My wife doesn’t do anything for me now. I’ve been with this girl and I am contemplating leaving her and our unborn child to go to Zimbabwe. I know it’s a risk but I don’t believe I’m just another punter to her.
What should I do? I think I’m in love with her.
