Most Helpful Girl
This is very common in many many many relationships. People get lazy and stop putting in effort. This won't be the last guy you see this with. Just because it is exciting with this new guy now, doesn't mean it will stay that way. The grass isn't always greener on the other side. Stop talking to the other guy for now and go talk to your boyfriend. You need to give your relationship a fair shot. If it doesn't work out between you, then you should go your separate ways. Worry about all of that before worrying about another guy.
