I need advice asap!

I think I want to break up with my boyfriend, because he doesn't make me as happy as he once did, and I love him still, but I do not love him like I used to at all, and he pushes me to do things I really don't want to do and usually won't take no, he's also really needy and very possessive and I hate asking him for permission on everything and I really don't know what to do. A part of me wants to give him another chance, but another part of me just wants to end it but I don't feel like I have a good enough reason to.
