Another setback...so upset!!!

So we they scheduled to start on 31 October so I asked my hubby to get with the PM for the schedule since they said it would be available the week before.  Well the PM informs my hubby that we have been pushed back yet another week, now starting on 7 Nov and that our settlement date now will be end of January to mid February...this is not what we talked about at all.  When we first decided, back in August, to get the house we were told that we would be settling early to mid Jan which was perfect as my husband's current lease is up 15 Jan and I would be able to travel during that time to be there for the settlement. 

I had to ask my SR why the push back - here's the email I sent:
Hi SR,

Hope all is well.  Rodney contacted PM to get the construction schedule for the house since we were told it was now scheduled to start on 31 Oct, well PM informed Rodney today that we have been pushed back to start on 7 Nov with a settlement date of late January to mid February.  Any word on the reason why this 2nd push back?  We are trying to schedule for me to be there for the pre-settlement/closing and Rodney's lease is up 15 Jan.  Any news would be greatly appreciated!  Thank you.  
Here was the response:
Yes - I wasn't aware of this until I got into the office yesterday. Basically, there was another contract written for December that took a long time getting loan approval. Originally, you were scheduled to start before them because they didn't have loan approval but they got loan approval last week so, because they were written for December delivery, they were prioritized for starting construction.
PM's normal schedule would have you settling in the first week of February right now. However, he beats his schedule by at least a week about 85% of the time. So I would expect you the be settling in the last few days of January. January 15th is not going to happen, but it is very possible to get you in January. There is really no way to know for sure until we get past the initial stages of construction. I would be contacting PM every week for an updated schedule (send him an email referencing your lot number and he will let you know what's going on) and we spoke yesterday and he understands that you would prefer to settle as quickly as possible. PM is really your best resource for up to the minute construction information so I encourage you to email and call him regularly for schedule updates. I'm sorry that your start got pushed for this other construction start, but it simply had to do with them being under contract before you. You didn't do anything wrong. It wasn't a decision that PM and I got to make - it was simply our office looking at the dates the settlements were written for and them not wanting a December settlement to have any chance of being pushed into February.
Let me know if you have any other questions or concerns. I know you're anxious to start! I will be taking pictures for you whenever you need - just remind me.
Thanks!  

I can't even put into words what I'm feeling...I don't know...I'm just frustrated...I know that due to military requirements I won't be able to take off in late Jan or early Feb so there go my chances of being there for the delivery of my house...and I fear with the winter weather right around the corner we'll be hitting more delays... :-(  Here's to hoping we start on 7 Nov!!!
