I am sorry you are hurting.

Honestly you only dated 7 months. It’s not abnormal to realize that relationship will not go further and there isn’t enough spark, and if the relationship has no future people know it within 6 months or a year. He didn’t drag you along

It doesn’t mean he had no spark to begin with. He maybe realized that there just isn’t enough to continue towards more commitment and he was honest and upfront about it. How much sooner do you expect people tell you? He didn’t know any sooner.

I also think it’s unfair to blame his mental health on not wanting to continue dating you. Do you think people with mental illness can’t make sound decisions when stop dating someone?.

Do you see a therapist? I’d recommend it

Hope you feel better soon
