I have been with my boyfriend for 8 months, and he treats me like a princess the way most girls wish to be treated, but I am 16 and he is 14 and things have got heated in the relaitonship, I feel ready to move the relstionship forward but I can't because he is underage.
Plus I don't feel what I used to feel for him anymore, I see him everyday in school and Monday, Tuesday, Wednesday, Friday and Sunday after school every week.
He can act immature and makes a fool of himself when we are out with his friends but when we are alone things get heated, but he isn't mentaly ready and is underage...
I have a lot of exams on at the moment and I need to focus on that, but then I feel like I am not giving him any attention.

We recently went on a break but he was texting me telling me he loved me too much and couldn't be with out me, this makes me feel like if I do break up with him I will be seen as the bad person and he will constantly text me begging for me to take him back...

What should I do??

1) definitely don't move 'things' forward with him. You both are too young.

2) if you don't feel the same for him as you used to, why string him along?

3) don't worry about being viewed as "the bad one", whatever people interpret it will pass

4) focus on your studies and enjoy being a teenager. Don't rush into doing adult things-you will have the rest of your life for that.

I don't know how to break up with him, I want to remain friends, we have been through a lot, but I just don't feel that "spark" anymore, I have been chatting to my male friends and a few seem interested in me, I just don't know how to let my boyfriend down easily, with minimum damage and I can't cope with him begging for me to take him back...

If you don't have the same feelings for him anymore, don't lead him on. Whatever you do, don't "move the relationship along" you both are too young and whatever you mean by that, it is very emotional and could ruin your realationship with him. It could also affect your friendship with him if you two decide to remain friends. So my advice to you is to tell him how you feel. Explain that there is an age difference and that you don't have the same feelings anymore, and that it's just not working out. Hope everything turns out okay. Good luck

YEAH!
You are not being fair to him. He acts like 14 year old act and it irritates you as it would most 16 year old. You two are in two different places.
End it before you really hurt him and please don't get into a sexual relationship. You are both too young and he is way too young.
