As Darren has correctly pointed out, you can fall in love as many times as you like, but that is not the issue, if you are married to Miss Filipina already, then you would need to start divorce proceedings against your current Filipino wife, and as you have a child who appears to be in your care, that can complicate matters, unless of course Miss Filipina is still resident in the UK.
Even if she is, there is the issue of custody, of who will be the resident parent, and who will be the non resident parent.
Then there is the issue of child support and of course financial direction arrangements, a divorce of this nature, where you have a child, can in some situations go on for about 9 months to a year, depending on whether you issue instructions to a solicitor, or if you could conduct the matter yourself, but its highly unadvisable, you should seek legal aid for your divorce as the costs can amount to between £12,000 to £15,000 if children are involved. (I have experience of this).
Secondly, then there is the issue of your civil partner, it appears then she is with you now, i.e. Miss Filipina no 2, if that is the case, and she is also married to a.n.other, if that marriage was to a Filipino, and her status is one of being a Filipino citizen, then the only way that marriage may be dissolved, is by viture of a legal anulment proceeding.
If she is British, then she may dissolve it by a UK Divorce, however, you can still live together without all of this complications in your joint lives, best of luck.
