<human>: My BF and I had been dating since we were in highschool. In our almost 5 years he fit really well in my family and established a strong friendship with my uncles and created a 4WD group. He loved me from the start and we were eachothers firsts. In highschool he was quite reliant on me as he didn't have many friends but after school once he stared 4WD he began to put far less effort into the relationship.

Quite often he wouldn't reply to my messages, would come to my house to spend time with me but would end up hanging out with my stepdad or on his phone. He would talk down to me and would rarely invite me to be included in his new friendship groups activities even though his friends would have their GFs there.

I know that I am a very caring person and often care to much but he would often dismiss me when I'd try to talk about these issues, making me feel stupid for worrying even though I felt unhappy.

I broke up with him at the start of the week because everyone I talked to says I shouldn't be with someone who makes me feel like that but now I am devastated. I can't eat, I take sleeping tablets but still wake up in a panic. I love him so much and I miss him like crazy but I think I feel this is the right choice. I just don't see how I'll ever be happy again or will ever be able to move on.

I don't know if I've made a massive mistake although he hasn't fought for me I reached out to him the other day and he just told me to leave him alone although he did say that he's heartbroken and can't deal with anything atm.

Can you summarize the given text in a few sentences?
<bot>: I felt unhappy in my relationship and all close friends and family told me to leave but now I'm heartbroken and wondering if I made a mistake.
