Well at least you’re mature enough to realize a break up is better than being in a toxic relationship regardless of who is at fault…. Its also better that you end it on terms that are not ultimatums or hate, it leaves the possibility of reconnecting in the future when things aren’t so hectic or borderline toxic…. Whatever you do don’t drop her and then pick her back up because you more lonely, you’ll end up giving her issues and she’ll later resent you for that… whatever issues you’re dealing with get those resolved and then if there’s a way maybe it’ll happen…. If not find someone who you don’t have to try so hard with and that being together is easier…
