Went through similar stuff when we first moved here. My DH couldn't sponsor us for a nearly eight months due to various reasons ,and hadn't much help or support from his Company except for words of doom like "send your family back, you won't get pataka for at least 2 years..blah blah"
Alhamdullilah though it all worked out eventually,without me and my daughter ever having to go back. So my advice to you is don't lose heart and don't give up. Be patient and act wisely. and as prism said everything will fall into place once you get your RP, Insha Allah.
