Probably because it will bring up all the bad memories.
You don't understand women

There are two possibilities
1) She is not interested.
or
2)
As usual very conservative lahat ng filipina and wants to play hard to get
She is probably the "Maria Clara" type.
I learned all about this the hard way. And I also learned about "indirect courting".
Another brand new concept.
Basically while my wife and I where separated I met another woman through a mutal friend.
Anyway I am a very bad flirt, and I also am very friendly.
Most filipino men are very shy.
So basically I ended up meeting her parents, I went to where she lived.
Of course being polite, I brought a gift to her parents etc.
And then I would always get her little gifts.
Anyway I thought I was just being nice.
Also I thought that she understood I was married, just have a few troubles at the time.
Anyway long story short, I ended up accidentally seducing her.
Again different culture, back home, we would just be having sex, she thought I was "indirectly courting" her.
She meanwhile ended up falling in love with me.
And later when I was trying to fix the damage I caused, she explained all this stuff to me, and I searched on google to learn more

I ended up getting stalked. When I tried to break it off.
And then a big scandal erupted (her family found out I am married, which I told her clearly before hand).
Anyway long story short, her family ended up having to send her to Singapore.
And I felt really shitty about the whole thing.
I had another GF. She said that most filipino men are good at the courting part.
But they are bad when it comes to "making moves".
And so even though she had many serious courters, that is why nothing happened.
I told her she should make some of her own moves, but she said she could not

Anyway I would seriously think about it.
A filipina may play hard to get, but when she falls, she will fall hard in love.
And then if you meet the family and all that crap, if it does not work out, there will be a big scandal.
Unless you are 100% serious, then don't do it. (or unless you are an butas ng puwit).
Also even if you do get married. What are your future plans ?
You seem a little young.
Just saying
