I'm with this boy, and he's really sweet, and I know he really likes me. He makes me presents and says he loves me all the time, but I don't think I'm really ready for a relationship. I don't know how to break up with him
if you can talk to him in a call or in person, then do that. but if you cant, write him a long paragraph about how you really feel. just tell him the truth.
try to recognize how much more painful this breakup will be if you do it later rather than sooner. breakup's suck no matter what but dragging it on can be far far worse. hope all ends well for you๐
