Why marriage is terrifying ?

I could swear from now that whatever am gonna say is the truth and nothing but the truth... I wonna ask you guys about the marriage in general from a personal issue? Am a 6'6 man with a n athletic body who's became an engineer while he was just 23 , am 27 right now with a my own house and my own small business, my income depends on the deal but it seems to be between 28k to 45k a month , I thought that am stabel enough to get married since I was 22 but after 3 honest relationships it looks like am cursed , I'll admit that I don't drink and am not social enough I always enjoy my lonelyness honestly, but I made the girl I like my own lonelyness to enjoy , my job is flexible enough although I may sometimes work as a model for my brother's business but I think that am doing my best , my issue that whatever I ask for my girl's hand it ends up with us separated once and forever sadly , I don't really know if am doing something wrong here or if I blew up something, I swear that I remember dates that I even remember the day we start dating and make it special every year , I call every day every night I always try to get along with her family , I try to spoil the one I love the best I could afford , I always no matter what cut a slice of my day of my life for the one I love , she is finally my life ! Sorry for taking that long but after I blew up the last one I just get depressed, and things never stop running through my head , I now that am not social and I don't have too many friends but I always try my best at anything... I may seems weird but I swear that this is my story for real? One year of knowing each other or 3 years together it didn't make a difference for me , I really hope to get some advices
