One Sided breakup

Help

Apologies in advance if this post is all over the place

I (22M) got with my GF (22F) when we were 15 years old. I lost my mother when I was young and I learned to grieve. My father abandoned me around the same time my mother passed away, but he re-emerged in my life and became a distant father figure (lives 1000 miles away). Me and her had been together for seven years with regular relationship problems. We have never taken a break, and the idea of breaking up has only been introduced once (3 years ago). When that happened, we worked together on a solution and we got back together and we’ve lived for the last four years 10 minutes away from each other. I thought the relationship was great.

Then on a Sunday afternoon, she comes over and out of the blue tells me that we need to talk. She ended our relationship because she “wasn’t happy”. I tried to work things out with her, but she says she doesn’t want to waste my time or her time trying to fix something she deemed unfixable. This tore a hole in my heart and I don’t know what to do going forward. Her mom and dad were both calling me every day checking on me but it’s been four days and they haven’t reached out. I just want to know that she cares about me still. I just want her to come back.

We also shared a dog together that felt like a son to me and it feels like I’ll never see him again.

Her mom and my dad both told me that in life sometimes people separate and then they end up back together and I want to cling onto that hope but it seems so far from the truth. I don’t have a support system around me to help me through this.

Please help me or give me advice for the future
