BM dropped YSD off 6 weeks ago and has seen her a total of 5 hours since. Not even picking her up for her oldest brothers birthday, when BM and OSD went.

Now it is common knowledge BM is a compulsive liar. BM has been living back with BF. She has to drive an hour to and from work everyday and also drop OSD off at her grandparents for homeschooling because BF refuses to be alone with her (completely understandable).  

BMs story to YSD is she and BF are broken up and she is looking for her own place. When she gets her own place she will start seeing YSD again.  BM has $10,000+ in tax returns plus all the stimulus checks, but she hasn't been able to find an apartment in 6 weeks??

In counseling BM stated in front of SO and YSD she is looking for her own place. SO came home reiterating this and his belief that it is the truth because she was very convincing.

Is he naive? Is it wishful thinking? 

How can he possibly believe she is telling the truth and not just perpetuating the lie she is using with YSD to avoid the truth and to still have YSD pining over her.

She has had 6 weeks to find a place, there are plenty available that are affordable.  She has more than enough money to move. She is inconvenienced daily with going out of her way for work and to drop off OSD.  She has made little to no effort to see YSD and why would she want to spend one minute longer with a guy she claims she doesn't want to be with?

Also why would he allow her to take so long GTF out of his house if they weren't together. She was homeless, couch surfing for almost a week after the girls attacked him.  It's also common knowledge he was planning on going for custody of thier kid. Why would he want to put up with OSD for one minute longer than he had to? I know I wouldn't.  

BM may be being honest that she doesn't care for him. But I'm sure he doesn't know that. BM knows he will get custody of the little one, she also knows she is all used up and isn't going to do better than current BF. BM doesn't leave any relationship until they either leave her or she has another man in the picture. 

When he kicked her to the curb 3 years ago she learned she wasn't going to do better and spent all that time trying to get him back. Ignoring both SKs that whole time to focus in being with him. Apparently SO forgot about that. He also forgot how she left 4 of her 5 kids behind when she moved across the country to marry some guy she met on the internet.

Sorry but I'm calling BS on her.
