I forgot to mention. We're having a baby.. Here's our short story.. last 2000 they migrated in the UK together with her family. They stay there for good. But of course she's visiting me here in the Philippines almost once a year.
Last 2010 she went back here to have her master degree.. Last year, she get pregnant (We're having a baby boy

) Then her parents advised us and insist that she'll give birth in the UK. So she went home last January of this year.
Our first plan is for me to go there for a visit during her due date of giving birth. But then we've decided that they will just visit me after giving birth. And hopefully we can process our papers, get married and we'll go together to UK.
Can someone advise please on what are the best actions or steps that we should do for us to live together in UK?
