Are my relationship fears realistic?

I've recently been asked out by a close friend who is in two grades below mine. I'm feeling really confused about what I want but I can't tell if my reasons for not continuing the relationship are nerves or realistic. I'm a very friendly person and I care a lot about my friends and this one recently got out of a thing with another friend of mine about two weeks ago. I don't want to hurt her if I dated him. I've also had a bad run with guys, with the past two emotionally abusing me and I'm nervous it will happen again. Then there's the fact that I don't want to hurt him if I freak out and suddenly end it because he means to much to me. Then there's the age. I don't care about the people at school but my family. My sisters will tease me and I'm pretty scared of them and their influence. I guess I just am scared of anyone not liking me and my decision. Is this realistic?

"I don't want to hurt her if I dated him" She shouldn't be hurt by this. She should understand that you have feelings for this person and it is your decision. If she is an understanding person then it will be fine. If this is a big fear for you consult her about it, ask her if you were date guy X would she get hurt by it? It's always best to ask if you don't know. "the past two emotionally abusing me" "I'm nervous it will happen again" It's a real fear to have certainly. It could happen again, but anything could happen. Not every guy is going to be the same, some guys with value your feelings more than others. Also these emotionally abusing relationships indicate you need to be more carefully selective of who you date, get to know them better. If they were abusing you with intent of making you feel terrible, if not did they mean to abuse you? Maybe you just perceived it as such. So just take every relationship as a completely new slate, that this is guaranteed to happen nor is it more or less likely to happen with a different guy. Just watch out for the signs that were prevalent in your previous relationships, and if they crop up again communicate with him and tell him this is not okay, sort it out before it breaks the relationship. If not get out of it. "I don't want to hurt him if I freak out and suddenly end it because he means to much to me." This is all indicative of a poor definition of what love is to you. When in or even considering going into a relationship you need a strong sense of determinism, meaning your in this relationship you're not going to back out unless the relationship takes a turn for the worst. You need to mainly though assess what love is to you, what's the difference between a friend, best-friend and lover to you? What do each give to you that the others don't? How far can you trust them? How far do you depend on them? What can you do around them that you couldn't do around other people or even to other people? You have to think things through, if he means soo much to you, you have to make sure you're making the right choice in that you do in fact love this person, you will in fact stick through this because you love him etc. Have faith in yourself too that you will do that. "My sisters will tease me and I'm pretty scared of them and their influence." This is a real fear to have. But again you'll have to deal with it at some point if you ever want a relationship right? Either way, try to limit what they know about your relationship, hide it from them. They don't need to know. If they find out, there is no way your gonna stop them doing what they're gonna do unfortunately, you can turn around and say they should concentrate on their lives and not yours. Try to influence them basically if that would work. What do you mean by their "influence"? Like they will try to damage your relationship through rumors or something? In which case, throw out a safe guard, warning your partner of this or friends. "I guess I just am scared of anyone not liking me and my decision."Most likely at some point not everyone is going to like your decisions on things. But they need to respect that, as long as you have thought things through and understand the consequences of your actions you should be fine. Ultimately this effects mainly you and no one else and your lover of course. Consider your friends feelings to make sure you're not carelessly hurting them and the obvious things like that. After you've heard of all the opinions of those you trust, make a decision. Note: When considering opinions focus on the points they raise, not their approval or disapproval focus on the reasons assess their validity and reliability. I hope this helped, good luck in this situation, have a wonderful day :D
