Help I’m in love with someone else’s man! He’s told me he loves me and wants me to have a child with him. I need advice.

I went on a date around a month ago he said he’d separated from her, so I believed she was the ex. They already have 2 children together and she has 2 from previous relationships. So the date quickly turned sexually as we are very attracted to each other. I could of happily continued as friends with benefits and seen each other when we could, but I think he enjoyed the wild and risqué sex we had shortly after a free days he’d came over to mine cooked which was amazing I wasn’t expecting anything at this point, but he began to open up more as I think he began to feel guilty he’d told me he only had one child but turns out he has 5month son he said he’s sleeping on her sofa but there not sleeping together which now is quite hard to believe. I did ask him why he didn’t say in beginning but the point is it was the beginning. Only thing for me to do is walk away I’m sure most would but I didn’t we continued sleeping together. Before he broke the news about other life I had told him I would like kids one day I may have to have <a href="https://glowing.com/glow-fertility-program">ivf</a> as it has been recommended and it seemed like he was on a mission to get me preggers he logged on my phone when we did it. Now I’m in the 2week wait and I secretly want to have HIS baby. He has got back with her which broke my heart. And he has contacted me since wanting to continue with me and getting me pregnant. I’m in bits because he was honest. And I still chose to stick around. Any advice out there. Advice or not I’ve now put it out there.
