Losing interest in my relationship

LadyB💕
So me and my SO have been through a pretty rough road. He has 2 kids from his previous relationship and things just aren't getting better. Seems like he doesn't want to do anything to settle things down and just so we could be more peaceful. I understand going through the whole court process is difficult but it would finally put everything into place. Seems like he rather just do as she asks then go through that and put a stop to her. She won't let him see the kids. All she does is ask for money. She doesnt work so he gives her everything for the kids. It's been almost 2 years but to me it's felt like 10! And at this point it's really getting to me. He's not the same guy who would really made sure I knew things would change for the better. Now he just rather take the "easy way out" In their case because it's just making things more difficult for us as a couple. It's almost a year since I've last seen the kids as well. I'm really getting tired of being me trying to push him to do things. And making me just loose interest in us.
