I realized that being the dumper is harder than getting dumped

I could really use some support right now as I just broke up with my bf yesterday, and feel horrible about it. I feel bad for hurting him but I feel it was the right choice. We were both getting hurt in a lot of ways. So I honestly did it for the both of us. He’s not taking it well and is angry which is understandable but I’m dealing with the guilt and the depression of letting go of him. Just bc I ended things doesn’t mean it’s not hard for me too, I’m really sad as he was a bestfriend too. We were together for 2 years and while a lot went wrong we also had a lot of great memories and I truly care about him as a person. I’ve tried to respect him and let him vent but now he is getting mean and it’s time to cut contact. I just feel so guilty ugh:(
