Should i break up with him and see other people? DESPERATE FOR OPINIONS!?

I've only been with my guy for 8 months so not quite as long as you two. I went through this to, especially during the summer. Just wanting something new. But then i thought about all the stuff we do together, the phone calls, texting, just always having someone who loves you to talk to. And i realized how much i'd miss him if he wasn't there anymore. I can't really tell you whether to stay with him or not. all i can say is before you make a decision like that consider how it'd be for him to NEVER be there the same way again because he probably won't want to be if he really loves you and you dump him. It'd be really hard for him to be around you and stuff.
