You are after a visit visa, not a family visit visa.
Like I say, YOU are the one to convince the UKBA that you will return when your visa runs out. If you cannot prove that you have good reason to return they will probably deny entry. The UK borders are really tightening up and we are trying to restrict illegal 'overstayers' so be warned, make sure your evidence is very strong that you intend to return to Phils.
