Ex & new guy 🤦‍♀️

Met a guy and we kicked it off so good, a few months down the track and we’re at that point of making moves to become official. When we first met, he and his ex were broken up but she wanted him back (after cheating on him) for their kids sake. He told me not to worry or let it get to him because he knows that it wouldn’t make anyone happy. Fast forward to now, my ex (father of my 2 kids who treated me like absolute shit) is begging for another chance, I have told not only my ex but this new guy that it would never happen and explained why . Now this new guy is saying he’s ‘unsure’ of what to do because he feels like he’s breaking up a home and that my kids will miss out on having their dad because of him. He kind of checked out at that point and I let him know I don’t want to be the reason he feels like that and we should take time to think things through. What I’m confused about is he went through the same shit with his ex and made it known he wanted me, I made it known I wanted him when my ex started so why is he now confused about where things go? I’m starting to feel like it’s his demons in his own mind thinking about him with his kids and how his ex will move on sometime too. At this point all the good has been soo damn good, but I don’t want to be with someone who backs out as soon as my ex asks for another chance.

Sorry just needed to vent !
