Another update: We talked for a long time today and have sorted things out. She has stayed with her original story but didn't really satisfy me as to why the calls went unanswered. I don't have enough evidence to openly accuse her of lying, so I'm going to trust that it's the truth or at least that there were only white lies. I won't be sending any more money though. The visa application has been lodged and I'll wait until we have much more time together before making any more financial investment in our relationship (other than the cost of the flights if she is approved for the visa).
We seem to be back to normal and I hope I've just had a case of LDP, but I'll definitely be a little more cautious and observant in future (without letting the paranoia get a grip). Thanks to everyone who has responded, you've been a great help and I'll give more updates in future. Hopefully happy ones
