Break from dating
Maybe it's not just work or your ex or your family. If you have a ton on your plate right now, it's perfectly valid for you to not have room for a relationship on top of everything else.But don't just leave this guy twisting in the wind while you figure out your other shit.Every interaction with him is driving you absolutely insane, and you're not sure if you're totally done with him, but you are sure you need a break from this emotional roller coaster. First of all, it's flattering that you liked him so much that it's driven you crazy. This one's a little harder to muster up the courage to do, but I'd say it's arguably the nicest way out of them all.If the reason you're over it is something he did and not something on your end, be straight up with him. Let him know you didn't like how he handled meeting your friends for the first time, so next time he meets a girl's friends for the first time, he'll know to be a little more friendly.But, if what you're looking for is more time to date around and see whom you're into, this excuse could be the nicest way to do it without blatantly saying, "You're not enough."Nobody wants to be with someone who's still in love with someone else.
You could be at a point in your life when you want to prioritize your friendships, and that's TOTALLY FINE. Sometimes you just don't totally click with someone.
Maybe you guys aren't fully getting back together, but you're talking again and it's just too confusing for you to have this third party involved. He might be frustrated at first, but eventually he'll feel better knowing the reason you ended things wasn't anything he did.
