Hi Applemisada, welcome to the forum.
In my opinion, I think that you could be playing with fire and could also be putting yourself at risk. Three months of on-line chat may seem like a life time to you if you are eager to take things to the next level, but your boyfriend may not have the same desire and a surprise visit might be the last thing he wants (particularly if he is already married or in a relationship, it happens!). There are parts of Essex that are very rough (some nice parts too) and I certainly would not consider putting my wellbeing and safety at risk for any man, particularly for one that didn't invite me to be there.
As for proving that you love him, you don't say why you feel this is necessary? Why not suggest that he goes to Paranaque to meet you first of all. It would be far easier for him to enter Philippines and he would also have a choice about whether he goes or not. You could then make your mind up about each other once you have met.
Good luck
Rosie
