Be there for him has a friend, but don’t let him rely on you. This guilt is normal and will linger for a while but do not give into it, if you go back to him, the same thing will happen again. He is only hurt because he had control and never though he would lose that control, he needs to learn his lesson so he wouldn’t do this to the next innocent girl. If you remove yourself from any toxicity to a positive environment then you are doing the right thing and should never feel guilty about that. Remember this is about your feelings and your happiness, not his. You’ve been under someones shadow for so long, it’s time to find yourself and love yourself and be your own person. I wish you the best, you deserve happiness, so go get it girl and don’t look back. If you have anything to ask, I’ll be more than happy to help. <3
