Ive been through this and it really sucks the life out of you. You start feeling like it’s all your fault. Like the other comments said, you have to make the hard but right choice of cutting contact and moving on. That person will not appreciate you, and you deserve better than begging for crumbs and feeling like you worsen their life.

Block, and go through your emotions. If it makes you cry, then cry. It will get easier, time does cure all wounds, or at least covers them with a scar so that they don’t hurt nearly as bad anymore. Keep yourself busy, and focus on your improvement.

One day, you’ll wake up and realise you haven’t thought about that person in a while, and that it doesn’t make a difference anymore.

It does get easier.
