well, perhaps you need to be a little more clear in your narrative because as far as I can see, there are few - if any - people who can understand it. "STD" to most of us means "sexually transmitted disease" ... I'm not sure was "vaction" means ... are you pregnant or do you have a sexually transmitted disease? Or both?
as far as your last comment,
anyone is good enough for
anyone to sleep with .... it takes a special someone to be good enough to make love with, share a life with, and parent with. If he doesn't think that person is you for him, it'd be a one-sided deal for you.
Good luck in the future.
