Don't ever do a friend visit visa if you're not in a relationship before at least 1-2 years!
The Embassy would not trust you!
Any immigration Office from a Schengen country (France here) would just denied it, thinking you'd do an illegal immigration! And make sure your boyfriend went 2-3 times to see you in Kuwait FIRST, before even trying to think about a friend visit visa C!!!!!!!!!!!!! ==> Proof you know each other, at least a bit!
Family/friend visa is probably the most difficult Visa C to get!!! Because you know someone in EU and there's a "high" chance you won't go back home because you're not coming from a rich country (unless you're rich... ==> show money)
if you do a friend visit visa, you'll have to proof you know each other, through immigration stamp to see each other / already travel together OUTSIDE your country / visa / pictures together / history of relationship + explain your future together and what you're planning to do next ==> living together/wedding in few years but NOT NOW/...
But they'll always wonder if you're not going to do an illegal immigration in Europe...
Forget it before at least 1-2 years of relationship ==> not credible!
Anyway, in both case, even if your boyfriend sponsor you, you'll have to proof you've have money/ownership/stable job/bank history & else to proof you've a reason to go back to "your country" no matter what.
You must proof you've no reason to stay in France because you have everything in Kuwait!
House/car/boat/family ties/whatever!
Did you ever use your passport to go outside Kuwait/Philippines?
You might also consider trying to travel together first to any other OECD country than Europe (any "rich" country where you need a visa, not just a stamp from a visa-free country (like Singapore or Malaysia))
==> South Korea, Mexico, ... (have a backup plan if the visa is denial)
Why?
Because if you get a visa from any "rich" country, you'll proof you can be trusted.
"You've been to a rich country and went back to your home without any illegal immigration." blablabla
And once you've received an OECD visa, you can go nearly everywhere in the world easily, even with your Philippines passport.
That would be a HUGE asset to your case!
Whatever which visa you're gonna do, remember to show as much money on YOUR side / valuable as possible!
In France, you need to have AT LEAST: 120€ per day if you stay in hotel, and 65€ per day if you're invited to your boyfriend's home.
So, better do a really short stays to get your first ever visa from Europe, then they won't bother you anymore if you did proof you can be trusted (and go back to your country).
Your target is not to spend a lot of time with your boyfriend (sorry), your target is to proof you can be trusted to get your first visa!
On the other side, a future denial of a "friend" visit visa "isn't too bad", it might also be seen an asset the day you try to live together in France.
==> they would know your story and the fact you wanted to be with him, it wouldn't be the first time you're telling the embassy you've a french boyfriend and so, "there's a story behind the future visa request"
My 2 cents from a Belgian guy in couple with Vietnamese girl with experience on the matter
