How do I get his parents to like me?

I don't mean to be rude sweetheart but if you said that to me I would never let my son see you again. You were both tested for STI and he was treated for something but the doctors don't know what he had? you are only 14 and have slept with 3 people, honey that is what is called a slut where I live. His mother had him when she was 16 so she is protecting him from someone like you because she wants her son to have a good future and not end up as a teenage dad. Sorry to be like this but that is the way the mum sees it and as for your other question about spells and witchcraft to get him back, I think you should grow up and get a life. Good Luck.
