Is it normal to focus on your partner as a major source of happiness when you fall in love?

I’ve always been a little bit depressed, it comes and goes. I always have to move around a lot for work so I’ve never settled in a place. I’ve been unlucky with work and other things.

Anyway, I met my boyfriend in June 2021. He was my first boyfriend and I wanted to see him all the time at the start. Is that normal? I kinda jumped head first into the relationship, I still went to the gym, cooked a lot and met friends but I still felt unfulfilled with my life, I dedicated my weekends to see my boyfriend as he was long distance

Got into a pattern of seeing him most weekends, he never planned dates I realise now… it was always me. He made me so happy, he was the first guy I’ve ever had sex with so that was very exciting.

Relationship ended last week.. he had pulled away emotionally.. said he was only with me because he was lonely. I feel ashamed because I’m worried that I ruined the relationship. I got depressed when he started putting zero effort in and I worked harder at that point to make the relationship work. He became my main focus and I kinda lost sight of anything else. Worried that means I’m broken
