HELP ME WITH MY SCHENGEN VISA

hi, to all of you and i hope you can help me out here especially who has an expertise with this. i live in the philippines, i am 28 years old and i am a single mother, i met my swedish bf more than a yer ago on a dating site, since then we have been chatting and having plans of meeting in person soon. we decided july because he was expecting that their company can give them a month long break which sweden usually does, their company did but was too late for him to buy the reserved ticket. we moved it this coming december and ill be the one to come there. i am so afraid that my application for visa will be rejected because we havent met in person which many usually do.. although i have my own money and online business which can suffice more than our daily needs, he takes home 19000 sek per month and has his own place to live in. he will guarantee everything and all the papers are set.. we chose this because this can give us much longer time to be together, instead of him staying for 2 weeks, we can get to know each other for 90 days.. the first plan was, my son will join me, but i decided not to because the embassy might think i will not come back.. so at least they have a reason to approve it..PLEASE GIVE ME AN EXPERT ADVICE, I AM SO WORRIED THEY MIGHT REJECT THIS.. PLEASE.
