Is He Making Excuses

My guy and I have been together 1 year.  We are mid to late thirties I'm 38 he's 36.  We have been TTC for 3 months.  We DO NOT live together yet.  Here's the issue... we fell in love quickly.  We wanted to live together almost immediately but decided to wait for 1 year because we both have children and wanted to take our time.  At the beginning he said he would move in immediately if we didn't have kids and marry me but that he didn't want people to question us since it was so early.  He said by the end of 2016/new year he would move in.  Well 2016 ends and I'm thinking he will be moving in and he doesn't.  He says he has a small debt he wants to pay off before he does as he wants to come into things debt free.  I accepted that but was disappointed.  So I tell him that I need to know because for me it's a finincial thing.  I cannot carry the mortgage etc of the home that I once shared with my ex and I need to sell if he isn't planning on moving in.   He knows my financial hardships right now.  So I hold on cause he says March 20th which is in 4 days.  Well we got into an arguement over something he son did to mine.  (Told my 5 year old there is no Santa)...Nothing serious but he didn't like that I thought his son was in the wrong as he knows not to say anything.  So now he feels he needs his weekends alone with his child for a while (says he doesn't want his child to feel like he can't say what he wants for fear he will ruin things for my child like the Easter Bunny etc). So of course I say does this mean your not moving in and he said he wasn't.  Is he stalling???? I think he is getting cold feet and is struggling with the transition.  Our children get along wonderfully aside from fighting like siblings.  He is amazing with my children and they love him.  I'm confused.  I feel like we are going backwards instead of forward.  Any thoughts ladies??? I know it's only been a year but when your older things tend to move quicker.  I feel like I'm good enough to impregnant but not good enough to live with and begin our lives together.  So as of now I'm putting the breaks on getting pregnant and putting my house up for sale.  I can't keep struggling for maybes.  So sad.
