How do I give my boyfriend a wake up call? (tell him he needs to make more of an effort or I'm out)?


We're in our early twenties, and have been together for 2,5 years, and lived together for 1.
We fight a lot sometimes, and overall I feel like he takes me for granted a bit and says really rude things to me sometimes. He does definitely love me though, and he definitely thinks we are gonna be married and have kids and so on later in life.

He's moving 1,5 hours away from our current city, to study (he's planning to stay there..) and he/we want's a long distance relationship.

Now, I'm all in for trying this long distance relationship, but I'm not sure it'll work out for me if he doesn't make more of an effort to spend time with me, and be nice to me.
I always let him know when I feel like he treats me badly, but he doesn't always seem to understand how serious I am.

SO how do I ONCE FOR ALL let him know that I'm seriously considering breaking it off with him if he doesn't put in more effort?
